Hi Dave from California,
I have recently hit a pot hole while going about 60-65 mph.....it jarred the right front wheel enough to make a loud snap sound. My 2000 XKR convertible drove ok on the way home....but being vigilant I took it to a repair shop to check the alignment. They told me the toe was out by 2 degrees and couldn't be put back in unless I brought it to the dealer to adjust the suspension with a shim kit. The car still rides well, it has a small wheel shake during the first 1/2 hour of driving and then it seems to smooth out, no shake at higher speeds. Is it normal to shim the suspension to realign? I have had all four tires rebalenced so I do not believe the wheels are causing the small vibration.
I actually think the tires need to warm up to round out so to speak.
Thanks for any comments
Dave

 

There are no shims for adjusting front suspension. But more important, toe is adjusted by screwing the tie rod ends in or out. I assume the shop you took it to actually measured the toe and didn't want to adjust it. You definitely don't need to visit a dealer to fix this.

 

Check for a broken upper control arm. It would explain the snap sound and loss of alignment. It looks like this

 

Many thanks to all who have replied to My post on alignment—awesome info and will use that to arm myself at the shop. Until next question comes up
thanks again

 

That is a strange diagnostic. Normally, the upper front shock mounts age very poorly on this car and lead to excessive negative camber. Sometimes folks are told to get an expensive eccentric bolt, but all they really need are new upper shock mounts. That excessive camber also leads to the toe being off. Toe is adjusted by adjusting the length of the steering arms (as usual). Caster is determined by washers on the control arm and typically does not change unless someone messed up a replacement of the bushings. For the rear, there is a shim kit for camber for sure. I believe rear toe is adjusted with an eccentric bolt.

I'd say open the hood and check the top of the shock towers. If the shock is no longer centered in the mount and/or you see bits of crumbling orange/yellow rubbery material, you need new mounts. Same if they are just old or with high miles. You can confirm this my looking up the proper ride height in the Vehicle Spec Book on jagrepair.com. Chances are you are riding low.

Best of luck, keep us posted.
