KSjeepguy88 Posted October 6, 2013 Share Posted October 6, 2013 Ok guys I'm stumped here, on my 88 MJ all stock. I've started to here a "rubbing/knock" when I turn left, Now it also dose it when the suspension moves. I feel it in my drivers floorboard. I just replaced the drivers side hub and U joint and they did seem to be bad but I still have this noise Link to comment Share on other sites More sharing options...

AeroNautical Posted October 6, 2013 Share Posted October 6, 2013 I had a similar problem, whenever I turned the wheel left it made a horrible squeaking noise. Turned out to be bad bushings, from the PO neglecting to grease em once in 25 years. Grease all the fittings on your front and just to make sure, if the sound continues it may be your steering gearbox or pump. Brother is having that issue right now, actually...

87manche1 Posted October 6, 2013 Share Posted October 6, 2013 Also check steering box bolts. Link to comment Share on other sites More sharing options...
KSjeepguy88 Posted October 6, 2013 Author Share Posted October 6, 2013 But the noise sounds like it's rotating when I hear it Link to comment Share on other sites More sharing options...
gogmorgo Posted October 8, 2013 Share Posted October 8, 2013 What size tires are you running? I've got a very similar condition on my '91 to what you describe, also when turning left, and I know my driver's side tire rubs my lower control arm. and possibly also my fender liner/ mud flap (they're starting to fall off) at near full lock, so I'm hoping that's all it is. I'm running 235/75-15's on (sagging) stock 4x4 height. But I'm on a starving student budget and I need my MJ every day and don't have much free time, so I haven't wanted to dig too far into it. I've picked up that corner by the frame and nothing seems loose, although the bushings look pretty worn out. My u-joint on that wheel does have a tiny amount of play, and my front driveshaft (1-piece pass axle shaft in a CAD housing) has 10-15 degrees play in the diff (with clunking sounds when turned back and forth) but I'd expect those to show symptoms on right lock too, not just left.

HOrnbrod Posted October 8, 2013 Share Posted October 8, 2013 Check where the track bar mount on the frame side. Sounds like the mount might be wallowed out or even the bracket bolts are loose. If all is well, then check the steering gear box bolts for tightness. Link to comment Share on other sites More sharing options...
KSjeepguy88 Posted October 11, 2013 Author Share Posted October 11, 2013 Ok so I had a friend get in my truck and rev the motor... I looked under the truck and every time he hit the gas the motor/trans rocked to the right side so much my new exhaust was hitting my crossmember and makes the sound. I need new motor mounts Link to comment Share on other sites More sharing options...
gogmorgo Posted October 11, 2013 Share Posted October 11, 2013 Hmm... my brand new motor mounts are only five months and 3000 miles old... but I'll check the exhaust. Check where the track bar mount on the frame side. Sounds like the mount might be wallowed out or even the bracket bolts are loose. If all is well, then check the steering gear box bolts for tightness. Do you know proper torque spec? Link to comment Share on other sites More sharing options...

KSjeepguy88 Posted October 30, 2013 Author Share Posted October 30, 2013 This is what my drivers side motor mount looked like when I took it out, Got the new ploy inserts in and no more sound! Link to comment Share on other sites More sharing options...
Me&my86MJ Posted November 25, 2013 Share Posted November 25, 2013 Yay!! I just got finished installing my new motor mounts as well. Interesting to know my Driver side mount was way more deteroated then the passenger one. Did you have similar instance? or were your mounts wore down pretty much the same? This seems to have fix my front end noise will post further it the noise returns or never went away. Link to comment Share on other sites More sharing options...
KSjeepguy88 Posted November 25, 2013 Author Share Posted November 25, 2013 My drivers side mount was in 2 peaces. The passenger side mount on my truck was all one peace but it was dry cracked and old. Link to comment Share on other sites More sharing options...
Me&my86MJ Posted November 26, 2013 Share Posted November 26, 2013 Exactly the same as mine. Do you have the 2.5l or 4.0? I got the 2.5l with 5speed np 207 I believe Link to comment Share on other sites More sharing options...
