- Leaf Spring suspension
- Dana 35 Axle (OEM)
- Detroit Limited Slip Differential (based on all of the pics on here vs. the pics I've taken it looks identical. thank you everyone for posting pics and links...very helpful)
- I am MISSING my rear sway/track bar (also, the lift was done with spacers by the previous owner and the leaf springs are shot...that's my big 2012 project to replace the suspension)
I used Castrol 80w-90 which says it works fine for limited slip...so I'm going to assume I don't need any additives at this point. While I was cleaning out the insides I did not see any gouges, obvious wearing, or marks that would indicate something was going horribly wrong.
The banging noise has been going on since I purchased my Jeep 2 years ago. It happens as I'm cruising to a stop or slowing down. I would say on average driving around town this will happen 1-2 times while running errands on city streets (all stop and go).
After I changed the fluid I still got a bang, but while testing out turns it felt a lot smoother.
How worried do I need to be about the banging?
Im still gonna guess that assuming the noise is coming from the differential and u have a detroit LOCKER that the noise is normal. Its not uncommon for autolockers to do this...but it sounds like the behavior varies from one locker to another.

That would not be because of a missing trac bar, thats more than likely a very bad steering linkage setup. The ONLY job of a trac bar is to center an axle laterally, that is; side to side. Leaf sprung axles do not need a trac bar, and in fact its 2 completely different types of suspension that contradict eachother. Why jeep put it on the YJ is completely beyond me. The only thing i can think of would be because the narrower CJ7 was more roll over prone, so the engineers must have figured a trac bar would help. To get to the point, trac bars are meant for coil sprung axles, not leaf sprung axles.. post a picture of your steering linkage and we'll try and figure out if that should be addressed.. It may also be that your tires need balanced, especially if its a speed-dependent wobble
I'm happy to see these last two posts as I've been experiencing the same thing on my 94. This is after I had a 35 rear end rebuild due to a piston bearing going out and bent rear pass. side axle and diff case going down. Now I have what I describe as a 'floaty' feeling while in a turn. Any suggestions/pics would be greatly appreciated. I've looked at/in/around the thing til I'm blue in the face. Love to see a pic of what one 'should' be looking like. I've looked and at best I find diagrams of parts, not an honest to goodness jeep steering linkage on a YJ.
