The repair shop wants to use the TR machine. > Does this do a good job, replacing all the fluid? Good idea. Look in your manual as to the recommended frequency. The fluid changing machines do a fine job, better than you can do by yourself, because they flush the torque converter too. That is, if the operator knows how to run it and isn't cheap with the flush fluid. > > b) Must the wheel bearings be repacked? Follow your manual's recommendations. I've developed a philosophy that as long as the grease looks clean and dry upon inspection, to leave things alone on the theory that upsetting wear patterns and the possibility (probably?) of introducing dirt into the bearings outweighs whatever benefits accrue from frequent repacking. This has worked fine for decades on a wide variety of vehicles. Still, I'd consult my manual if it were mine, just in case there's some special condition involved. > > c) Do the spark plugs need to be replaced?

Thank electronic engine management and clean, lead-free fuel for this. It really works that way. My wife's Camry had 150k miles on it when she wrecked it - all on the original plugs. Toyota recommended changing at 60k miles but I decided to wait until either the mileage dropped or the ECU dropped a code. Neither had happened. Amazing, eh? Anyway, again, check your owner's manual for recommended change intervals.

Apparently this works, as one trailer is almost 30 years old and another is 10. I believe that the probability of doing more harm than good taking the wheel set down so often. Wear patterns are disturbed. There is a probability of introducing dirt into the bearing cavity. Of mis-seating or damaging the seal. Of mis-torquing the axle nut. I base most of my decision on my racing experience. In the beginning I followed conventional wisdom and pulled the bike or car down after every race for inspection and wear parts replacements. I had the same rate of niggling failures that everyone else did. I analyzed my logs and saw that most failures occurred to things that had just been messed with. I stopped messing with things and my failure rate (and DNF rate) went WAY down. John From: John De Armond Newsgroups: rec.outdoors.rv-travel Subject: Re: Preemitive strike on MH?

Depends on your definition of "defective". I routinely listen to the belt-driven accessories with a mechanic's stethoscope. If I hear rumbling bearings, squealing seals, dragging brushes, etc, I replace the accessory at once. In my mind the device is defective even though it is still working normally. Some folks consider something defective when it quits working. > My motto is, if it ain't broke, don't fix it! Which leads to the corollary: if you don't take care if it, it becomes broke sooner and then you get to fix it, potentially under unfavorable conditions. John |
