I'm mostly looking for a sanity check to see if my thinking makes any sense. While I certainly enjoy tossing large sums of money at my coach, I generally like to see some improvement as a result. To date, the results have not been good. Thanks in advance!! 🙂
I've been fighting a fairly significant vibration on an MCI coach (102-EL3) for a couple years now. In general, it starts at 55mph is bad up thru 63 mph and is tolerable at 66-68mph. It may be better when cold - definitely bad after being in operation a while. Up/down hill doesn't matter. Coasting downhill doesn't make any difference. I won't bore you with all the details but will say that I've had every king pin, bushing, rod end, etc... replaced that mechanics have even given a second glance, all eight tires, four wheels, Road Force balanced all eight wheels/tires at least four times each (different shops), replaced tires, used Tru-Balance to mount wheels, etc... I have never tried balance beads and nobody has spent much time looking at the drive shaft.
It makes complete sense to me that my problem is not the wheels/tires (given two different sets of tires and the number of times the wheels/tires have been balanced - perhaps the brake disk or ???). I was looking for a shop that would perform an on-vehicle balance and ran into the threads here about the Centramatic balancers. I haven't yet found such a shop in the NM area so was thinking of tossing another thousand $$ at it with these Centramatic balancers.
Sound like a logical next step? Or, do you know of a really good shop that will do on vehicle balance in the SW (NM but I would go to PHX if there was optimism).
