This group provides a forum for owners and operators of diesel powered motorhomes and 5th wheel tractors to discuss mechanical issues, regulatory issues (US, Canada), ownership, insurance, campground accommodations, trip reports/suggestions, and other topics relevant to large RVs and the people who drive them.
Argh, at the local gas station, fixin the brake squeal (gone now) we found that the tie rod ends on the passenger side were loose. Ordered the new ones, in fact ordered both sizes because we did not know which size we needed. Gonna pick them up tomorrow & hopefully getem in before leaving for Mazatlan. (Nate if you have your chauffer's cap, you kin drive)
My cruise control is a sometimes thing, when it decides to take control, stabbing the brake pedal turns it off. Try that next time you get the runaway. If that does return the go pedal to normal, it is the cruise control who has decided it knows better than you how fast to go.

Problem solved. The very loud (think hammer on muffler) noise described as "whang, bang, & clang" which struck fear into the heart of my passengers - and was not discoverable through any exterior inspection turns out to have been a dry rear CV joint which was noiseless on flat ground for 1000's of miles, but which had worn (gouged?) metal out of the joint, so that on a long protracted run on a 6% grade, the joint apparently separated just enough to make you think you were in a boiler room.
There are 3 such grades going into Las Vegas. My new axle & CV joints were as quiet as a thief at midnight. Problem solved.
PS - Mary's optimum cruising speed is 81mph.
brian from laverne (sitting in his hotel room in Las Vegas)
My car's bike rack smashed the lid to my trunk after a big rearender. It still
opens and closes. Just looks really bad. 77 W123 body. 240D. If I can get
time on a frame machine it will be back to somewhat normal.
Yes, cruise control, under the theory that it sticks when the revs get a little high.
Do you have any suggestions to the revving issue or are you questioning the usefulness of the theory?
Thanks
