Wj This Rear Lower Control Arm Bushing Bad?

Got some noise from the rear passenger side, when I had some work done on the frame at the start of the winter it was mentioned my rear passenger lower control arm wasn't great. Searching the forum/internet didn't reveal if these cracks are normal after some use or replacement time, so asking you here.


When my front ones have been bad the metal tube falls right out, this isn't, so please let me know on the cracks.



Thanks.

That control arm is not dead, but dying a slow death. It may not be the noise your chasing yet, but it will be soon.

Good enough answer for me. It's an original arm on when I bought the jeep over a year ago and I beat the heck out of the thing delivering mail. I'd rather replace it now vs while it's not snowing.



While I've got it up & am replacing them, anything else I should check/replace (only things replaced since I got it on the rear end have been the upper real control arm & breaking stuff, no other suspension)?


Springs aren't cracked, shocks aren't leaking, but didn't take off the stabilizer bar to check that.


Thanks.

If I were you I'd go for the Superpro bushes in the lower arms.

Yes they're more expensive but they provide a massive handling improvement with no negative effects AND if you plan on keeping the Jeep they'll save you money as they last for ever.

Did mine 5 years ago and it was the best decision I made for the Jeep!

I have a 99' WJ 120K...I'm getting the dreaded Rear-End Clunk, which is probably the Upper Control Arm and or Ball-Joint...So, I'm getting the Upper Control Arm w/Ball Joint, Lower Control Arms, and End-Links from Crown Automotive.

After that I will be replacing similar Suspension Parts for the Front-End in near future.

I found the companies website but they don't sell directly. I found some on Amazon but don't know how to find ones for my control arms. Any tips?

Here you go:

I'd also recommend the panhard rod bush kit... removes most of the dead zone in your steering

Thanks. Looks like e-bay's my best bet, $125 for both sets.

It's beyond dead. I mean these are some serious cracks. You can better appreciate bad bushings when all the weight of the vehicle make them go off center. Even a bit of center is bad.

Rockauto has plenty of options for the whole assembly. I'm sure you don't want to reuse that pile of rust. Personally went with ACDelco; $100 for the set.

OH HOW MY JEEP IS A PITA!


So I made a homemade press with old bed frames I had. That took a couple days but worked out pretty cool. Had issues with the jack. Fixed it. Then yesterday I jacked up the car, took off the control arms, burnt out the existing bushings, used the a wire brush on my angle grinder to clean them up, coated them in rust-converter stuff, then painted green. Turns out I couldn't get the existing sleeves out so I had to cut the sleeves off the bushes I put together in the picture & put the bushings directly in the arm. So I got the new bushings in the driver control arm no problem. I got the eye-shaped one in the passenger arm, but the round one wasn't tight. In fact, it had space to wiggle around!


I decided to go to town & get another bushing, thinking i messed up with what I ordered, but when I get to Advanced Auto they take a stock bushing and it's to small! So we compare my control arm to a new one had the round hole on mine is the wrong size! GAH! Whomever had the jeep before me must of put on non-correct parts "because they worked". I would of done that too, but at least made a note of it.



So I just bought a control arm for the passenger side & put it on. I was finally done by 6pm on Sunday and wanted to give up so I can release for a couple hours. In a couple weeks I'll take the rear passenger control arm off & put the new bushings in.

Eurgh that is a pain. Does this mean you've got superpros on the driver side and rubber on the passenger side?

Thanks. It's the result of having more crap around & not wanting to spend $$.
