2wd rear tyre wear

**Cossiedan83** · 19-08-2010, 00:34

My sapph wears the inner edge of the rear tyres really bad i must be honest she gets a good hiding but by the time the tyre is bald on the inner edge the rest of the tyre is ok i know you cant adjust camber or tracking and it does'nt look like the arm bushes are worn and shes still standard ride hight but not sure when springs we're last changed ???????????????

i had this problem when i upgrades to poly bushes in the rear trailing arms, ended up changing them back to Ford item, (which have a rose joint) in the middle as i found out trying to burn the original item out !!
The poly bushes are not rose jointed, once i went back to the ford items it still happened but not as bad, i had the car for 5 years and was wearing the outor edges when i bought it and decided to upgrage, then went back to ford items.

Its a standard thing for Sierras. The lower it is the worse it gets.
You can fit washers between the hub and rear arm were the front two mounting bolts are or get some shims that do the same job. Its not the best solution but will work.
Or get an adjusable rear beam, not cheap.

New stronger rear springs may help too.

i think Reyland do a spacer kit for the rear end to help overcome this. I run my 3dr quite low, and its kiils the insides really quickly

I'm using the camber shims for some years now with no problem at all (drifting with -0,5º of camber in the rear). Just make sure you do the math before puting them on so that you don't get the camber ruined.

If you split them in half it's really easy to put them on without taking the hubs off.

good luck!!

I'm runing -2,0º camber in the front and -0,5º on the back but the car is very low and rock solid with 450lbs on the front coils and 350lbs on the back. If you need anything just ask
