The front mount is hydraulic. It's a known fail point.

I'm guessing at the cost here, but labor is about 1.5 hrs, and the part
will be close to $200, if not more. The bill may be on the order of $400,
plus tax.

However, there is a TSB out on this (06-014) covering all '99 3.2 TL's. The
TSB specifies that the repair "MAY" be eligible for "goodwill" warranty
coverage, even at this very late date. If you have a very good relationship
with your local dealer, you may get lucky here. It's certainly worth going
in to talk to your service advisor about this.
