Hi hoping someone can shed a bit more light on this subject and my options:

Just had my 1990 Buick Century 122,000 miles at an alignment shop and they did they alignment but said that the Driver'* side Caster should be 1.2 - 2.2 degrees but is at -0.1 degrees because the under chassis engine cradle has been pushed back from the car bottoming out on the driver'* side (these cars sit too low if you ask me).

So they said I can replace the engine cradle to fix.

Since the Caster does not effect the tire wear should I just live with it or it there another way to adjust it (like by changing something with the strut top mount or pulling the cradle forward etc?

Thank-you

Caster should affect stability at speed.

What rjolly87 said ^^^^^^^

. . . and it will affect tire wear.

The question is: Is the cradle bent or deformed or is it just moved backwards?

Sorry I’ve been busy!

Here are some pics of the cradle.
i thought it just had some typical dents from bottoming out as these cars easily do.

Also here is a big thing that may be unrelated:
When driving on the highway things are nice-tight-nimble BUT when going over a wavy-up and down bumps on the highway that make the front end move up and down, the front of the car moves a noticeable amount from left to right.
The alignment guy has said everything else looks good and tight.....
Ive looked under it myself for loose rack and pinion mount or something else but I didn’t have a buddy to turn the wheel as I watched and I suppose I’d have to stress the components to see any suspicious movement..
Do these cars have a known problem for these symptoms..?

Thank you for any help and expertise!

If it can't be brought within specs there'* something bent or a bad bushing etc.

The driver'* side of the cradle looks messed up. Appears to be some sort of collision damage.
Too bad it'* the driver'* side, it is welded. The passenger'* side can be unbolted from the front of the cradle.

Miiiiight be able to align it out. Might.
