How technical of a job is replacing front sway bar links and rear shock
absorbers in a 2000 LW2? Can a reasonably adept person do the job with a
good floor jack in a residential garage?

And will the car need re-alignment after the new sway bar links are
installed?

Thanks!

Replacement is not real difficult.
I suggest using ramps, the more room the better.

I don''t believe that you will need an alignment since all they are are rubber bushings/inserts.
