My 1998 Z71 is becoming a money pit. The right rear tire was making a high pitched whinning sound on the highway, sound got quieter when I slowed down. Got home, jacked up truck and tire moves in and out about a 1/4 inch. Just in towards the axle and out, so I dont think its ball joints or anything like that. Any ideas? cuz I'm tired of dumping money into this thing, I hate to get rid of it, bodys in great shape.

 

could be axle bearings or could be a problem with the diffrential

 

is there an easy way to find out which it is?

 

not really......you just kinda have to "tear" into it........unless someone has any other ideas

 

How deep is the pit? If you keep throwing money into it, it's bound to fill up and be a money pile soon, right?

 

If your truck is paid for, and my '98 is, even if you drop $1k/year into that thing you're WAY ahead. Trust me, I don't like that every month or 2 I gotta fix something on it, but knowing that I don't have a truck payment on one that's a little bit newer also goes a long way. I say fix it again.

 

Yeah, I guess your right. I usually do my own work, is this something I can do myself? People I've talked to have said it is most likley the wheel bearings. Any diagrams any where I can download?

Go to the site - I think you have to register but it's free - and you can save your vehicle and it gives you decent repair info and diagrams. Not sure if it will cover your particular problem but it might - and of course, it will also give you the price and availability of the parts you're looking for

 

Take it to a shop for a diagnostic check. The check should be free. My friend had his checked at a trany shop for free. And if it is bearing do both sides. Remember both sides have the same amount of wear. And I feel it is internal with that much slack. Is there slack on both sides of the rear end (I mean will both tires move in and out)? If so, I think it definately would be the internal workings.

 

I don't think its the bearing. I think its a retainer clip in the differential at best. I hate to say it but it might be the rear axle going bad.
