LCA bush failer question

[davenorton]

I have a puzzle for you learned folk. I have a 91 IC , 165K 5 sp. After purchasing 4 years ago, I did all the common R&R stuff including the LCA bushes. I had sadly purchased all the stuff from a vender selling off brand stuff. I did both sides correctly, a few k miles later the right side bush failed. Assuming a bad part, the vender replaced it. The replacement bush, same side failed a few K miles later. Wanting the bad news to end, I got a pair of off set Lemforders, you guessed it, the drivers side failed again. Looking carefully I cant see damage to any suspension members. I have no unusual tire ware, or drive-ability issues. What is wrong? Should I just replace the control arms and start over?

Use soapy water to help the bushing slide onto the end of the control arm. Once you get the bushing on, you need to bolt it up and put the car back on the ground asap before the soapy water dries. When you put it on the ground, the control arm shaft will rotate to it's normal position in the bushing.

If you don't put the car on the ground before the soapy water dries, then the bushing will be preloaded and will fail prematurely. I have a sneaking suspicion this is what happened.

Hi Dave

What do you mean by "failed"? What happened?

What happened? The metal cylinder at the center of the bushing is firmly on the peg end of the LCA. The rubber separated from the inner cylinder, stayed connected to the outer cylinder, which is firmly in the lolly-pop .

The other idea raised in a post that too much time elapsed between pushing the lolly-pop over the LCA and lowering the car, is a good one. However, if I recall, anticipating that potential, I did one side, lowered the car to proper positioning , did the other side the next day. Also the second failed bush described in the story posted previously was done on its own, while the other two non failed bushes, I did the same way. I "think" i am doing the job correctly
