1987Comanche Posted March 24, 2013 Share Posted March 24, 2013 I replaced Georgia's LCA bushings yesterday and noticed the upper bushing on the pass side is in bad shape. At ride height (weight on jack stands) it seems like the oil pan would interfere with a ball joint press/C clamp. The driver's side seems to have plenty of room. When I did UCA bushings on my '90 4WD the engine was out so there was plenty of room. What's the best way to replace the UCA bushings with the engine in? Support the body & let the front suspension droop? Will the axle shift when the UCA is disconnected (happened on the '90 and was a PITA to line back up)?

HOrnbrod Posted March 24, 2013 Share Posted March 24, 2013 I was able to swap the UCA axle bushings using my homemade redneck bushing press. It was tight but worked well. I had the axle resting on jack stands. The axle will twist if you let the suspension hang down, as you know, creating said PITA. :eek: Image Not Found Link to comment Share on other sites More sharing options...
1987Comanche Posted March 25, 2013 Author Share Posted March 25, 2013 Am I correct in assuming you meant UCA but typed LCA instead? The threaded rod cleared the oil pan on the pass side? Link to comment Share on other sites More sharing options...
HOrnbrod Posted March 25, 2013 Share Posted March 25, 2013 Am I correct in assuming you meant UCA but typed LCA instead? The threaded rod cleared the oil pan on the pass side? You are correct on both counts. Now I'll correct my original post. :yes: Do you have any lift at all up front? Link to comment Share on other sites More sharing options...
1987Comanche Posted March 25, 2013 Author Share Posted March 25, 2013 No lift at all. Bone stock 2WD. Speaking of there's a lot of confusion on the upper control arm bushings. The local parts store only lists bushing for the 4WD axle...Moog K3128. Do 2WD and 4WD use the same bushing? I called Moog tech support and the guy could only tell me what he read on the computer...

ComancheKid45 Posted March 25, 2013 Share Posted March 25, 2013 AFAIK The only difference between 2wd and 4wd front suspension is the coils and the axle itself. Link to comment Share on other sites More sharing options...

The LCAs, UCAs and associated bushings are the same for both 2WD and 4WD. The Moog K3128 is a kit of two bushings for the UCA, is correct, and is what I used on my 2WD. :thumbsup: Also, I highly recommend installing WJ LCAs instead of just changing bushings in the old ones, especially on a mainly street truck. They are full tubular, much more solid, and make a world of difference in handling as the bushings are larger. Link to comment Share on other sites More sharing options...
1987Comanche Posted March 30, 2013 Author Share Posted March 30, 2013 Changed these out last night and posted some pics of the removal/installation tool(s) on my build thread. I used Hornbrod's idea for a tool as a basis for mine. 4WD bushings fit the 2WD axle with no issues. http://comancheclub.com/topic/37173-georgia-92-40-ho-ax-15-2wd/page-2 Link to comment Share on other sites More sharing options...
HOrnbrod Posted March 30, 2013 Share Posted March 30, 2013 Good idea on the 4.0 rod cap for the bushing bracket "ear" spacer. :thumbsup: Link to comment Share on other sites More sharing options...
