I have some extra time on my hands and am thinking of replacing my
bent control arms. The only problem is I do not have anything to
fall back on to make sure I am doing it right. Has anyone had any
experience replacing a control arm and are able to provide some
kind of guide?
Its for a 1995 XJ6 both rear driver side and rear passenger side
control arms need to be replaced. Currently started on driver side.
Damn those curbs
Thanks for any help provided.–

Upper and lower?
Givent hat you condemned the curbs, I’m guessing lower…how did

ahah a year a go I hit the passenger side and yesterday I hit the
drive side. Now they are both bad so I think I should replace
them. Right now as far as I can see it is lower. Is there any way
to determine which of the two or both are bent?–

I believe HMS is questioning upper and lower control arms on the
rear. That would be because there is no upper, only the drive half
shaft, which I very seriously doubt is bent.
I have rebuilt the rear end on my XJ6, and the best advice I can
give is buy the CD, or a subscription to Alldata. Either is worth
the small investment to get pictures and instructions.
Also, instead of replacement, I straightened mine by gently heating
the center of the arm to a very dull red, with one end in a big
vise and a pipe affixed to the bolt holes on the other end.
In order to check for alignment on the rear end, I have had good
results with a laser level and a ‘‘target’’ card checking the rear
end alignment. Basically, for setting toe, you shoot the laser
along the side of the car at the height of the wheel center and
offset the laser line equally from the front and rear edge of the
rear rim, then measure distance from the line to the edge of the
front rim, with the wheels turned straight. For camber, a plumb bob
establishes vertical, then check offset to top and bottom edge of
the rim. If the wheels are cambered approximately zero, and the
toe in is zero, and the axial center line is the same distance from
a known point on the car (like the axle mount bolts), then your
rear end is aligned. It ain’t really rocket science, just geometery!–
