Rear suspension seams to shoot on our 04 outlander,rear wheels are tilted wearing out the inside of the tires what do we need to do to fix this problem

if the wear is on the inside of the tread ---wheel bearings , failed suspension bush,arm
if it is on the outside of the tire tread ,-- bent lower control arm
if it is patchy around the tire ---failed shocky
it is appears as if the tread is feathered towards one side of the tread--- wheel alignment
Tack it to an accredited suspension specialist shop for a proper examination and a rear wheel alignment

well if its a nascar race car your speaking about then that's called Positive camber !!! and it makes you go faster in the turns ! cus there always turning left !!! if its not a race car your speaking of , then you have a bent front axle it will make the tire loose traction easier and it will make tire wear out faster

this is from suspension bushes worn out , weak springs and wheels out of alignment. It is essential that the rear suspension be repaired and a rear wheel alignment be carried out to fix this problem

I replaced the rear struts, when removing i discovered one was totally bad, they didn't seem bad from testing and recovered quickly when pushing on the bumper, but were bad. after replacing my rear tire wear is even after 5k miles. mine were wearing from inside to outside too.

No solution yet but have same prob on my 03. Rear tires shot after only 10000 miles. NTB gonna diagnose for free. Got 4 tires and 4wheel alignment last year from them. Service mgr thinks it's prob suspension but will prorate michelin tires. Betcha it'll still cost me a thousand. :(

Yes there is adjustment. You need to get the alignment checked out. It could be worn bushes and/or damage to the suspension linkages and struts.

Had a similar problem with a different car. Rear struts / spings were worn. Caused rear to sag enough to push wheels out and wear out inside portion of tires.

car needs to have the rear camber alignment adjusted .thats the angle of how much the wheel tilts in and out when looking at the wheel

Wow you have picked my brain from 1989 when I was in the body shop business. I used to fix fiberglass vehicles and most were corvettes. The older guy I used to work for showed me how to set the rear suspension up and we would jack the back of the car up and turn a cam and nut on a trac bar. The tire would be tilted at about 3 degrees inward (bottom of tire). You then would lower the car and the tire would set almost straight... I mean .... (ever so slight tilt). It has independent suspension as you well know and if you have checked the u-joints this is the next try. Worst case, a good alignment shop can fix your woes.
