Steve,

That price seems "low" to me... You are correct that the LCA is
supposed to be replaced as once piece.  II priced the LCAs for my 96
Maxima last year and the original nissan part was abuot 200 bucks.  Are
you sure that price you were quoted was not for parts only? I would
expect the job to take at least an hour per side and would plan on
replacing the swaybar endlinks (and endlink bushings).

I know of some folks who have replaced just the bushings and
ball-joints seperately, but neither are services performed by "dealers"
and you'd have to find an independent mechanic who could take on that
work.

Having said that, if you can find a dealer to replace the LCA for 200
bucks, including a genuine Nissan/Infiniti part, run there and get it
done ASAP :), heck get both sides done and take in a box of bagels for
the service dept ;)

Cheers,
Nirav

You can buy just the bushings for the lca in the 93 maxima.  I would
imagine the same holds true for the Infiniti.  Courtesy Nissan in texas
