Lower control arm Poly Bushing

[Robsweden]

Hi

I thought of changing the lower control arms, and box the new ones. Also I would like to get some poly bushings in. I bought what I thought was right but this is the fitment. The shell is from the old arm.
Will It compress and work when torqued down ? I think there is to much play. The measure is 1 7/16

I don't think that will work. The inner sleeve won't permit compression/expansion of the poly bushing. Chuck

Yeah that won't work at all. Bushes are friction fit - they aren't supposed to slide or spin around in their seats. They work by deforming within their material.

Yes My thought to, Well Il go hunting for some others. I think the 1 9/16 are the correct ones

Here is the finished product, Boxed all around and 1 9/16 bushing from Energy suspension. The old shell is welded in. Polybushing are wrapped in telefon tape before putting them in.

Steps:

Press out the old Bushing with shell
Drill out and press out the center of the bushing leaving the edges inside the shell. Use heat to get the rest out.
Polish inside the shell with scotch brite on a cordless drill
Make a template of the control arm and trace it to the metal
Prep the arm for welding
Clamp to the arm tight
weld in short session so not to much heat is presented
Sand the welds if you need to
Paint the arm
Drill the hole with a holesaw for the sway bar bolts
Press in the shell and weld it on one side to the arm, repolish if you need.
Prep the bushings with telfon tape and press in
Install in car
