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.
A suspension part has come loose or is worn out. Check the top strut mounts under the hood. There may be a rubber plug to remove to see the top mounting plate. The three nuts around the perimeter of the strut plate are the mounting nuts, not the larger center nut-leave that one alone-it is for keeping the strut from coming apart. If that mount is good, check for a broken coil spring around the strut. Keep looking for the problem. If the tire leans out that bad, you should be able to spot the problem. Raise the wheel off the ground (recommend jack stands or blocks so it won't slip off the jack), grasp the wheel and shake it back and forth while watching for looseness or noise on the suspension parts connecting to the wheel hub at top and bottom- the upper and lower control arms and the strut connection. Good luck.
Check your rear suspension. Load-leveling air suspension struts could be bad or leaking. Air suspension compressor could be inoperative. Air suspension compressor relay could be bad. Air lines from compressor to struts could be leaking, from cuts, cracks, or having rubbed through against the frame. Transverse leaf spring could be sagging.
And it's Toronado, not Tornado. Sacrilege!
The air suspension system should stay up for several days without going completely down, which probably means that you have a small leak which is quite common even on relatively new air bags or struts.
A general rule of thumb is that if the compressor isn't kicking on several times during a drive then they are good to go. The air bags are a pain to change, so most people don't change them until they are really bad.
IF self leveling (gas struts) are faulty,when you come to a stop after driving for about 10 mins,the rear will not have risen to level.(still low).then they will need replacements fitted,they are not that expensive,compared to some air suspension types.(just in case im not clear,the rear pumps itself up AFTER moving off/driving and will settle when stopped for awhile after.)
the pump should be underneath the trunk behind right rear tire, if not follow the noise when the pump is running - the leveling switch is on the rear suspension arms - sounds like the pump is not pumping enough air or you have an air leak in the struts
