I haved a 98 and it ran me about three fifty. The parts should be about the same. 140 or so. But its the labor that will change a lot. It just depends on the shop.
If you need to replace the lower ball joints, check your owners manual for instructions. The manual should show you the location and how to complete the repair.
There isn't one. The 1995 Grand Marquis uses a lighting control prossessor. They are very expensive to replace. The part cost me $325.00.

A 2000 Grand Marquis does not have struts, it uses a conventional shock/spring type suspension.
A dealership would be able to replace the key.
Requires special equipment, like a press set for the lower ones, better to take it to a shop, since you'll have to have the suspension aligned anyway.
