Hendersons Line Up
Just got back from visiting Henderson's Line Up -- a wheel alignment
service specializing in RVs that also manufactures the SuperSteer product line that upgrades RV suspension components. My coach had a pull to the right that didn't seem normal -- and I'd developed a considerable shake in the front end that felt like badly balanced tires. After a test drive and inspection these problems were found: 1. The Blue Ox True Center steering control unit, installed by the previous owner, was bent and jammed -- accounting for the pull to the right. Henderson's commented that this unit had been recalled. I now realize that it wasn't working from before I took delivery of the coach. Mr. Oliver's (the dealer) wasn't familiar with the system and had commented that "it didn't seem like it did much." 2. The drag link tie rod end was worn causing significant play in the steering system. 3. The left front tire was out-of-round -- due to abnormal wear caused by the damaged/worn components, a serious flat spot had developed. I had to buy a new tire. (A Les Schawb Tire Store is nearby their location.) 4. The left, front upper shock mount had cracked and slightly pulled away from the frame. Due to scheduling and the need for parts to be shipped in, Henderson's removed the True Center device and I got a new tire. I then drove on to Junction City Oregon where I had an appointment for installation of a desk by Davis Cabinets. During this approximately 300 mile round trip, I noted significant improvement in the handling of the coach with the damaged True Center device removed. However, there was some "wander" in the Wanderlodge movement down the highway. Upon return to Hendersons they: 1. Aligned the wheels. I discovered a significant out-of-alignment situation that would have quickly ruined another tire if it wasn't corrected. 2. Installed the Safe-T-Plus steering control with remote trim adjustment system. 3. Welded the shock mount back in it's proper place. 4. Replaced the entire drag link (including tie rod connections at both ends). Initially, only the lower end of the drag link was to be replaced... however, it was not possible to remove the old end from the link without risking damage -- so it was decided to simply replace the whole thing. 5. As part of their service, they weighed my coach. Interestingly, there is a 2500 lb difference side to side at the rear axles. Apparently, this is simply a design issue -- and probably an issue with the diagonal/side aisle floor plan. While all major (heavy) components appear to be mounted on/near the coach centerline, it's obvious that _something_ is not fully counterbalanced. (The personal items in the coach were randomly distributed and should have, if anything, reduced the difference.) The technician, using weight and inflation charts for my tires came up with an alternate set of tire pressures (and adjusted them) that reflect the actual loading. It was significantly different than that suggested by Blue Bird. BB suggested F-115, D-110, T-90 and the new values are F-90, D-115, T-100 on the light side with T-120 on the heavy side. In retrospect, this 2500 lb difference is not a highly significant amount considering the overall 47,250 lbs. weight of the coach at the time it was weighed. (Fuel 2/3 full, fresh water 3/4 full, black/gray tanks empty.) I note that the only item that falls completely on the heavy side is the fresh water tank, but it weighs a maximum of about 1000 lbs. I also note that there is considerable remaining capacity as the GVWR of my coach is 52,500 lbs. 6. The technician was unable to tighten the end of the steering gear (at the bottom of the steering wheel shaft) because BB had wrapped an incredible amount of wiring across the area and it was impossible to reach the necessary components without risk of disrupting the wiring. If there is an actual need for this, it's a relatively minor aspect of the project. Results: In a test drive and in the 400 mile trip back home, the handling of the coach felt much better than it had before -- it was hard to believe that it was the same vehicle. The deterioration of the ride had been gradual, so it was a surprise to realize how really bad it had gotten. We discussed installation of the SuperSteer Motion Control Units -- a device that attaches to each of the air bags to help with sway or bounce in the suspension. (I deferred installation for "later.") However, during the 'after' test drive, the technician admitted that motion control units would only marginally improve the handling of my coach. (Keep in mind, this is the 95, 42 foot model -- it might offer a greater improvement on other models.) All in all, I was highly satisfied with the products and services that Henderson's provided. While the process took a bit longer than anticipated, I can't fault them as it was primarily due to the need to obtain parts once the specific problems were determined. At no time did I feel that I was given a 'hard sell' nor did they talk me into buying unnecessary services. (For example, they might have sold me shock absorbers, but, instead, they simply cranked an extra 'turn' into the adjustable Koni shocks on the coach.) One final observation -- even with the improved steering/suspension, many of California's freeways are still in sad shape and will shake the bejebers out of you...

Hi Pete,
I had just about the problems when I got my PT-42. Cracked shock mount, pulled to the right, drag linkworn out, all the tie ends worn out, and a binding steersafe. My BB guy told me that was common with the 42's. If your coach is like mine it drives a whole lot better. Mine still is very senitive to steering wheel input. The only cure I've found is kinda like in baseball, choke up on the wheel. I drive with the spokes on the steering wheel about half way between the wheel and the horn for most highway driving less input, less motion, better control, you'll be surprised at how well she will track. One word of caution I have a tendency to drop my thumb into the cutout on the spokes of the steering wheel. Not a good idea especially if the wheel spins around or jerks hard to one side or the other. Newest PT 42 problem: Air cylinder for left rear drive axel brake fell off this morning. Caught that mess a little late. I backed over it! The only good news is it happened in my driveway and not on the road.

Kurt,
Cracking shock mounts have me a bit concerned. How many miles are on your coach? Have you checked the ride height? Have you checked to see if the shocks are bottoming before the airbag bump stops?

Hendersons Line Up
One (left front) shock mount was cracked. The coach has about 130,000
miles. Henderson's checked the other factors and determined that the shocks did not need to be replaced. The pull to the right was due to the True Center system that was bent and jammed. Once it was removed and the new tire installed, to replace the out-of-round one, (before the other repairs could be made due to waiting for parts), I drove 300 miles round trip to another vendor for installation of a computer desk that was scheduled. Upon return to Hendersons, the other work was done. During the 300 mile trip, the coach handled "100% better" than it had since I originally took delivery. There was only a hint of 'wander' that I attribute to (probably) the worn drag link end. After the new drag link and Safe-T-Plus were installed, the wander was eliminated. I can remove my hand from the wheel (briefly) and the coach will (now) track straight down the highway (as most vehicles will). I don't find the coach to be overly sensitive to steering input -- I've also learned to give the system time to respond to inputs and this may be a reflection of my steering technique based on my experience with other vehicles over the years. I don't have the "thumb habit" you mention. Hopefully the Safe-T-Plus will moderate any sudden wheel jerks due to uneven pavement or pot holes...(that's the idea, anyway...) Loss of the air cylinder is a thrill... of course you drove over it. That's par for the course! =============================================== Pete Masterson, Author of Book Design and Production: A Guide for Authors and Publishers Aeonix1@...

Seems like not enough miles for ordinary metal fatigue
to set in. Is there something else going on? Perhaps when the suspension air is dumped, the weight of the coach comes down on the shocks, not the bump stops. Could be that the Koni's are too long for the chassis/suspension, or it could be that the frame pick up points are woefully under- engineered. At this point, I think we should all go out and check our shock to frame mounting points for cracks. David Brady '02 LXi, NC Pete Masterson wrote: > > One (left front) shock mount was cracked.

Another scenario that could excessively stress the shock
mounts (assuming they bottom before the air bag bump stops) is releasing the HWH jacks before adding air to the bags. In this case the coach will come down quite hard onto the bump stops or shock mounts, whichever hits first.

That's an interesting idea... and might be a possibility as I've
noticed that the coach comes off the jacks fairly rapidly. I'll make my procedure to 'air up' before raising the jacks. I usually need the air pressure for the waste water dump valves anyway as that's a 'last thing' before departure from most places where I've used the jacks. The technician at Henderson's didn't speculate on the possible cause of the break (after considering that the shock might have been too short). The failure was pretty obvious, so I'd think that it would have been noticed when the current shocks were installed. I don't know if there's something different about the left vs. right side ... the right side didn't show any signs of fatigue.

On my LXi, the original spec was for firestone air bags
and monroe shocks. The ridewell suspension was installed and jounce and rebound travel was spec-ed with the firestone air bags and monroe shocks; i.e, the air bag bump stops limit jounce and the fully extended shock limits rebound travel. Well, firestone air bags gave way to goodyear, and monroe shocks gave way to koni's. Turns out the goodyear air bags give more suspension up-travel before the bump stops hit plus the koni shocks are longer in the fully collapsed position. In addition, the rubber bump stops yield upon impact. This all adds up to a shock that gets real close to bottoming before the bump stops hit, or during bump stop deflection (when releasing the HWH jacks for instance). With the firestone and monroe combo things were already tight. We need to watch this, cause I've heard of quite a few owners who have had problems with shock mounts ripping out.
