Rear End Problems

Here's one that's been stumping me for a while now. I can't seem to keep rear tires on my truck. (Definitely not from burn outs) The truck simply chews the rear tires off. I have never gotten more than 18k out of any size, shape, or make of tire since the factory tires. I have changed the rear end fluid twice, added friction modifier, etc. Fluids look fine, nice and clean, not burnt, and gears look brand new. No welds, etc... Any ideas? Has anyone else had this problem? I would love to get some more mileage out of a set of tires!! Thanks for any help!

Re: Rear End Problems

Do they wear evenly? Do you pull anything? Rotate much?

Re: Rear End Problems

I had rear end problems about a year ago. Went to the doctor and showed him and with a little time with the knife I was fixed. The healing wasn't fun as it could have problems but it's all good now. Jokes.

Have you had a wheel alignment to check? That is the weirdest problem? Do they wear evenly?

Re: Rear End Problems

Also what pressures are you running?

Re: Rear End Problems

Have you checked to make sure your rear axle is not moving. I have seen it severall times were teh rear axle has walked breaking the spring center pin and staying in that position for years before anyone noticed. All looked good and tight untill we pulled apart... Get a 4 wheel alignment

Re: Rear End Problems

Hey guys thanks for the replies! To answer some questions I always run my tires at the recommended max pressures. I am running 285/75/R16's at 65 psi currently. I do tow, I work in excavation so I have a trailer on with equipment relatively often. I have had it aligned but it has been some years, so that is a good idea to check, thanks! Also, I check my truck over often and have never noticed any pins being broken or my rear axle moving, but I will be sure and double check that, good thing to watch for. Also, a tid bit i forgot to mention, on pavement when I turn tight say in a parking lot, the rear end growls and has a subtle vibration you can feel/hear at low speeds... Thanks for the ideas !

rear end could be going south on you locking up on turns... Or you have some sort of limited slip in the back?

When we fount the broken center pins we did not know until we pulled it apart. everything looked good and tight and no movement by hand

Re: Rear End Problems

ZRock, I'll be sure to check those pins. That has me wondering now. And I'm afraid of what you're saying about the rear end going south... it seems as though it gets worse the older / more miles the truck gets. It does have a limited slip rear end in it. Anybody have ideas or good places to look at rear end parts ie factory limited slip rebuild kits or elockers?
