Dick, if these bearings are truly multiwrenchinal, then they should also be multimufflered. They should fit "cherry bombs", "smitty's", or "glasspacs". If you don't have a bearing for each side just hold 2 for the same side. When I install them I'll just turn one upside down.

Thanks, Nick

are they the ones that fit the large tail pipe at the end or the standard one that is on the rest of the coach?you know that most have the large end piece so everybody thinks that are that size and not the smaller one..I am lucky I have the larger size all the way threw.So save me two large ones with the wrenches mine have expanded in the last hour.
thanks lenny

Dick, Nick et al.
Just having a tot or two of Baileys with my coffee this morning and it came to mind that if these bearings are not available I found the mains from my old Norton Commando worked well. Just be sure they are the later "superblends" and not the earlier variety that were so prone to failure in high heat apps.
Have a happy Sunday.

Nick.........I guess if you had two from one side you could put one on aft-forward and the other fore-aftward, it wouldn't look very nice...but who looks?

Don, you've triggered some memories, there. Present 850 Commando has Superblends, (and is not ridden as hard) but when I raced a 650SS/Atlas, mains were the bane of my existence. I was always alert for that ominous, but almost imperceptible rumble that meant a day wasted in replacement. Before the Superblends came out, I got mine from FAG, I think. In my own case, I did not think temperature was a factor. Certainly, Willow Springs and Riverside had a wide range of temperatures. I think my engine mods stressed the bottom end more than it was designed for. (It started life as a low-compression, single carb 500.) I had so much compression that only White-Pump Chevron was suitable, and with a too-wild cam, had to start it on soft plugs and change after warm-up.

I thought, "Why is that Frisbee getting bigger and bigger?" Then it hits me...

The vibrations I was sensing seemed to come from the back - today, on my way back from Green Bank, WV, I was on a very smooth section of I-77, so that the road surface had no effect.

Then it occurred to me that the driver's seat is right over the front axle...and I was able to feel the shimmy in the steering wheel. I'll take it in later this week for alignment and check of components.

And with the new motor mounts, the engine's not thrashing around wasting energy - fuel economy is up again...from 10.5 to 11+.

The mechanic discovered a badly worn left king pin, and a set is on order. Interestingly, the service manager mentioned that the ones installed use teflon bushings, which tended to wear easily. The replacements are steel/bronze.

Do they still ream kingpin bushings?

The king pin already done reamed these. I don't think it's legal anymore.

StaRV II is on the road (RV park in NC). The drive up produced what may be mixed results.

The vibrations at 55+ are much reduced, but they persist - and come and go. One theory is that the roadway gets "scalloped" due to heavy trucks, and this is causinig the primary vibration. This has been (maybe) verified, as the vibrations disappeared when I passed weigh and agriculture inspection stations, where truck traffic would be minimal.

Epilogue (I hope)

Another trip to truck tire place because the shimmy persisted; they rebalanced all six tires, and it seems to be solved.

I had mysterious shimmy/imbalance problems on 2 vehicles, a Chev pickup, & a GMC motor home. In both cases it turned out to be misalignment/displacement of the steel belts. It was easy to detect in both cases, once we got the rigs off the ground, spun the wheels & watched the tire tread wobble.

In the case of the motor home, the previous owner spent hundreds of dollars in several shops across the U.S., re-balancing tires, replacing wheel bearings, etc. A friend of mine, hearing my complaint about the intractable problem, pointed out a wavy tread on one of the rear tandems while the coach was sitting still; an improbable problem, but easily corrected by replacing what appeared to be a perfectly good tire, once the displaced tread was discovered.
