TJ Front Upper Control arms

Post by Slewis » Fri Jun 21, 2013 10:06 am

I'm gonna be replacing my front control arms on a 98 TJ and am wondering if there are issues anyone has run into. Is there anything I need to plan for, tools to buy? etc. How much of a pain is it getting the stock bushings out for the uppers?

Also are the stock bushings something that can be picked up at any parts store?

Are you certain the bushings are bad? It's a real pain to get them out and new ones in, and most of them I've seen were just fine. You'll need at least a ball joint press, along with preferably a shop press, a hacksaw blade, and some patience to replace them. I cut out the old bushing and outer sleeve, then pressed the new bushing into the new outer sleeve, then press in the inner sleeve, then press everything into the axle.

I haven't done a full inspection but by first glance they don't look good. They are the only bushings up front that are original, I'm getting a clink/clunk at low speed turning like something is moving around up there. They are the originals with 150K+.

I'm starting the process of putting in a new suspension and would rather make sure everything is nice and tight from the get go.

Fair enough, I understand wanting to make sure you do everything right the first time. The front bushings have held up for me for well over 150K, but if there's any doubt go for it.

Just to be sure, have you checked the ball joints, and made sure the tie rod clamps aren't getting in the way at full lock?

You may want to check your wheel bearings too, it's free and easy. Jack it up, grab the tire at 12 and 6 and see if there is any movement. My jeep made a weird binding clunk at low speed turns when that went bad.

Something I have to look at as well. My plan is to spend some time inspecting the front end and make repairs as needed. It drives a little squirrely and makes a little noise.

I already have the control arms so that's my starting point. Next will be ensuring the track bar bushing is good, I have a suspicion it is either bad or the bracket holes are ovaled.

Bearings should be good...I think. I know I replaced one, can't remember if I did both or not.

Should is a bad diagnostic method.
If replacing control arms, either go aftermarket or buy complete stockers (or get good used ones for free) and bolt 'em in... I'd never try to replace bushing on stock sheetmetal arms.
97 TJ. It has some stuff.

I got aftermarket. I'm talking about the front upper bushings at the axle end.

Started late today. Stock upper bushings on axle end are fine. Got passenger front arms in, after spending the majority of time on a seized bolt in the existing bds lower arms. Heat didn't work, had to cut it out. :evil:

Passenger bearing is good.

I think my biggest issue are frame bracket bolt holes being a little worn out. I got my rear upper brackets fixed last week. The front is gonna have to wait.

im going to replace upper control arm bushings that appear to be aftermarket adjustable and lower control arms all together that i think are already aftermarket as well because there not the horseshoe shape sheet metal looking ones i was hoping someone can give me some advice how hard will this be if they already are aftermarket? i do not have air tools or specialty tools just basic wrenches sockets hammers ect can anyone tell me of this is doable and if so how hard, possibly provide instructions somewhere
