Toyos, installed about a year ago. We get rain nearly all year, I have done country roads just fine. This was just a stop light. We haven't had rain since June. I think the roads are just glittered with oil, and I completely underestimated it. Of course, anyone should have better grip tires. I just upgraded the front control arms last week, and it handles different but thats no excuse. I shouldn't have been confident.
those control arms and spindals are the same in all 89-97 tbirds so you should be able to find another in a junk yard and swap out the parts not really all that hard to do you'll need an alignment afterwards and if you take it in to do the alginment and they say it doesn't have rear wheel alignment leave and take it elsewhere cause they are clueless. Just make sure when you get another spindel you have a new wheel bearing pressed in
You'll want to replace the whole wheel assembly. I brought Lazarus back from a direct impact on the passenger wheel. Upper and lower control arms, axle, knuckle, and new alignment. You can change those parts in an hour, there's only three bolts. The alignment is the biggest delay.
The aluminum Mark Viii arms are a nice upgrade...
I agree with the guys saying to replace as much as you can get your hands on for the LR. Metal fatigue is invisible to the naked eye and after a shock impact like that, there's guaranteed to be lots of it throughout the area.
Here are two examples of an IRS ( the first one is what I have on the SS .. the second one is an aftermarket Art Morrison IRS kit. Notice the Upper control arms are not designed to be an "impact absorber" .. what you gain in stiffness by re-enforcing the Tbird UCA is to improve ridigity for hard driving situations. 🤔
