bhorocks Posted November 29, 2007 Share Posted November 29, 2007 after doing a 5 inch lift on my mj i am getting some bad wobble. trackbar is nice and tight so i measured my caster and it is at 0 degrees.

1999MJ Posted November 30, 2007 Share Posted November 30, 2007 you should have 7 degrees negative caster Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted November 30, 2007 Share Posted November 30, 2007 Here is what Mine is set at. I have almost 7" of lift and no wobbles what so ever. Image Not Found Image Not Found CW Link to comment Share on other sites More sharing options...
Twisty Posted November 30, 2007 Share Posted November 30, 2007 I have between 5 and 7 degrees. The return to center is still very much there, and no vibs at 6.5" of lift. Link to comment Share on other sites More sharing options...
HOrnbrod Posted November 30, 2007 Share Posted November 30, 2007 I have between 5 and 7 degrees. The return to center is still very much there, and no vibs at 6.5" of lift. X2. 4-7 degrees is good. Link to comment Share on other sites More sharing options...
mjeff87 Posted November 30, 2007 Share Posted November 30, 2007 just SOA'd the MJ with 1" longer fixed LCA's but stock UCA's (about 5.5-6" lift total) and have 10 degrees neg caster :oops: No vibes, and good return to center, but had to pull the front DS because of the bad pinion angle. Got a new set of RE adjustable UCA's going in next weekend to fix it all, and am shooting for 5-7 degrees when I do. Jeff Link to comment Share on other sites More sharing options...
bhorocks Posted November 30, 2007 Author Share Posted November 30, 2007 right on. I pulled just one shim and it seems to be doing soooo much better. got close to 4 now. Prolly pull the other one this weekend and see what i get. I also pulled the steering stbalizer seeing how it needed replaced also. handled great without it though compared to earlier today.

JEEPERZ Posted November 30, 2007 Share Posted November 30, 2007 right on. I pulled just one shim and it seems to be doing soooo much better. you pulled a coil spring spacer(shim)?? what shim did you pull? Link to comment Share on other sites More sharing options...
Twisty Posted November 30, 2007 Share Posted November 30, 2007 There are shims that go into the LCA mounts on the axles. At least I think thats where they go. Anyways...those control caster. I adjusted mine with adjustable upper arms. Link to comment Share on other sites More sharing options...
bhorocks Posted November 30, 2007 Author Share Posted November 30, 2007 the shims right behing the LCA. Link to comment Share on other sites More sharing options...
bhorocks Posted November 30, 2007 Author Share Posted November 30, 2007 I adjusted mine with adjustable upper arms. I would get the upper arms but i want to save that money for a long arm. Link to comment Share on other sites More sharing options...
Twisty Posted November 30, 2007 Share Posted November 30, 2007 I adjusted mine with adjustable upper arms. I would get the upper arms but i want to save that money for a long arm. Wise choice. I purchased my 6.5" springs, adjustable UCAs/LCAs and an adjustable tracbar for $240 from a local club member . Other wise I would have long arms :D Link to comment Share on other sites More sharing options...

Twisty Posted November 30, 2007 Share Posted November 30, 2007 Twisty.......you suck....... :D I just dropped 2 bills on RE adjustable uppers! Jeff You will be glad you did! I recently "alligned" my MJ, and tightened up loose bolts (I found 1 LCA bolt and 1 UCA bolt loose). The steering has NEVER been so perfect!

Twisty Posted November 30, 2007 Share Posted November 30, 2007 here's a somewhat helpful quote... If you don't have adjustable control arms, caster can be changed by using a shim behind the pocket for the lower control arm. The heavy-gauge metal of the Drop Bracket (and the stock LCA pocket) is slotted, while there is a metal 'C' that wraps around the control arm bushing. On the back of that 'C' are two studs that poke through the back of the LCA pocket. By inserting the shim between the 'C' and the back of the pocket, the control arm is moved forward, tilting the pinion down slightly more. here's the link...little more then half way down. http://www.yuccaman.com/jeep/re_db.html Link to comment Share on other sites More sharing options...
bhorocks Posted November 30, 2007 Author Share Posted November 30, 2007 nice find that is exactly what i did except i removed one instead of putting them in! Link to comment Share on other sites More sharing options...

I adjusted mine with adjustable upper arms. I installed brandy new brackets in the DB's when I did them. All my adjustment is from the JKS and RE adjustable CA's.

JEEPERZ Posted November 30, 2007 Share Posted November 30, 2007 it looks like you guys are checking caster without the coil spring in. is that correct. and if so where do you put the degree finder if the coils are installed? Link to comment Share on other sites More sharing options...
TNT Posted November 30, 2007 Share Posted November 30, 2007 right on. I pulled just one shim and it seems to be doing soooo much better. got close to 4 now.

You should have added a shim or two not pulled one. You reduced your caster... :nuts: You need positive caster.... :roll: Link to comment Share on other sites More sharing options...
Twisty Posted November 30, 2007 Share Posted November 30, 2007 it looks like you guys are checking caster without the coil spring in. is that correct. and if so where do you put the degree finder if the coils are installed? If all the CAs are bolted up, then you can check it without the spring in place, because the spring just sits between the frame and axle. The axle will not move when the spring is installed.
