Im asking here because everyone in tech and general are looking for floor mats and wax. I know there is real car people in here. I had my diff rebuilt at RPM about 5000 miles ago and its been great. Stage 3. I jut replaced the half shafts about 3000 miles and has been great..now my left tire gets about 60% of the wear as the right. Drives normal. But when i push the car when it is off, i feel a popping every half tire rotation...nothing is leaking...i also run t1 sways and they do pop here and there but this is def drivetrain related....thoughts?

Are you asking two questions or one?

Tire wear and drivetrain dynamics?

When was the last time you had an alignment?

Left tire -- both front and rear?

how is the left tire wearing? Post up pix of both tires, especially with a depth gauge in different places along the width of the tire.

Do you track the car or just is it just a street machine? If it's just the street, then your alignment/tire pressure is most likely the problem...or possibly a bad tire.

You can also check to see if they put the "limited slip additive" in the diff when they rebuilt it. I don't put it in mine (because I race it) and it pops a bit when turning slowly. Street cars should use it though.

If you track it, check the corner weights and make sure the car is correctly corner balanced.

And you can also check all the bolts holding holding your diff in place...otherwise this could be happening to you: http://www.youtube.com/watch?v=P0lSxBC2cjM

They are drag radials so reallu no tread depth...and it just rears

Go get an allignment check... if the toe is off it'll wear out a tire extremely fast. The rear diff shouldn't pop when pushing the car back/forth in a straght line. If that's happening you may be hearing the half/shaft splines clicking in the area of the axle nut. Happens from time to time. You can loosen the nut then retorque to 119 ft/lbs (factory spec). If you want to get really fancy you can shoot some grease in the splines and try to get it in there w/o having to take the hub off.

If it's chattering when you make tight turns you need more limited slip additive. Most aftermarket fluids like Redline and Amsoil ( I use Amsoil ) have it worked in and don't need extra additive, but sometimes they do. Squirt a 1/2 tube in and go drive a few tight figure 8s in a parking lot to get it worked through the limited slip.

That said, none of that should cause tire wear on one side.... worst case scenario the limited slip could be bad and putting more power to one side... my 2WD Nissan Titan has an open diff and when I dog it it'll spin the RR tire only.

Thank you! Im gonna check that hub nut

Just a thought, but if you get on the gas hard enough to get some rear wheel spin and your corner weights are off, you are likely always getting more wheel spin on one side. Given the left/right imbalance of the car with the driver on the left, it really wouldn't surprise me to see more wear on the right if wheel spin off the line is the predominant source of wear. If your tires are not directional, rotating them left to right would equalize this.

They are the newer 18" mt drag radials. So they are directional and have a good sidewall and corner well. Rarely do i spin the tires taking off because its mainly used for taking cornets hard and high speed.
