[V8] Subframe bushing replacement... issues

[NIck Miller]

Well, you can get them cheapest at Stopshopanddrive.com  At 4.95  or from
Autohausaz.com for 7.10 or so.  I got mine from the auto haus though,
because it is cheaper overall with free shipping on my order, and most of
their stuff is cheaper than the competition.

You can either go to a shop for alignment, and they tell you its broken...
or you can look at them and see if they are getting rotten or cracked.  Or,
when driving and putting the car in gear you may feel a little bit of a
shake, shimmy, bump, or etc when going into gear, pressing heavily on the
gas, or letting up on the gas after accelerating heavily.  Um, I think that
sort of covers it?  The front ones are recommended to be replaced between
120-150k MI, by SJMauto.

Uuuum.  I don't know if the rears can be replaced, as I don't know where to
find the part.  But from what I've heard/read they do not go bad often if
ever.
