deziped Posted August 20, 2012 Share Posted August 20, 2012 Anyone know the OEM bolt size that goes through the track bar bushing at the axle brkt? The bushng & brkt are wore out & the bolt has gone bye-bye. I looked here but only found the torque specs. http://www.geocities.com/JeepI6Power/1989XJMJ.html Link to comment Share on other sites More sharing options...
mvusse Posted August 20, 2012 Share Posted August 20, 2012 I believe it's 10 mm, but may be mistaken. Link to comment Share on other sites More sharing options...
HOrnbrod Posted August 20, 2012 Share Posted August 20, 2012 Correct. It's M10x1.5x70. Link to comment Share on other sites More sharing options...

Stacks Posted August 21, 2012 Share Posted August 21, 2012 Just an FYI for you too. I have found on my TJ and my MJ that the bolt diameter does not match the bracket or track bar sleeve diameter. The bolt is undersized and that causes some slop. I have carefully drilled out the track bar sleeve and the bracket to accept a 7/16" bolt. This gets rid of the possibility for movement on that end of the track bar. Makes the steering much more positive. Hope the helps!

xj92 Posted September 13, 2012 Share Posted September 13, 2012 If you get a YJ bushing, it fits in the stock oem track bar, but uses a 1/2" bolt. Just FYI. I used that and drilled the hole bigger on mine. No slop as mentioned by stacks. Link to comment Share on other sites More sharing options...
Eagle Posted September 13, 2012 Share Posted September 13, 2012 Just an FYI for you too.

I have carefully drilled out the track bar sleeve and the bracket to accept a 7/16" bolt. This gets rid of the possibility for movement on that end of the track bar. Makes the steering much more positive. Hope the helps! I have found that the 10mm bolt fits a new track bar perfectly, but if the old one was allowed to slop around too much the hole in the axle bracket may become enlarged. The factory setup uses a nut with a tab, which makes life much easier. On my '88 MJ, I found a double thick, heavy pattern, hardened 10mm washer and a friend welded that to the fact of the backet for me. No more problems. Consider that a 10mm bolt is .3937" in diameter. A 7/16" bolt is .4375". That's a difference of .0438, which is 3/64 of an inch. If you have to drill out the 10mm hole to allow for that amount of difference, how much slop could there really be? Not much. Link to comment Share on other sites More sharing options...
