JBA Offroad Upper Control Arms And Suspension MEGA Thread BS thread

Mine did the same thing... and here's why.

When I went to grease my UCA's, I loosened the UCA bolt until it was VERY loose (nut just barely on). I pumped the grease and tightened it back up. Here's what people fail to tell you. After you've tightened everything back to spec, you need to take a pick and poke the zerk, to allow the pressurized grease out. As you tighten the UCA bolts to spec, they'll capture the new grease in there and not let it purge out from the cavity. Purging the zerk after you're all torqued will relieve the pressure and they won't blow out.

Lessons learned...

Edit: Here's a good resource video. The pimple popping begins at 1:44.

Too bad they don’t have a relief port like some large electric motors have.

 

If you grease them with the bolt lose, then remove the zerk before you tighten the bolts, the excess grease should flow out of the hole. Then after its tight, just put the zerk back in.

 

I'm running with the big dogs now. No issues with greasing the new style bushings, no bent sheet metal and aligned to 3.2 and 4.0 positive castor. Steers fine. Drilled and cotter pinned the UCA nut too. Bilsteins riding smooth...........

 

Your paint job came out 100x better than mine.

 

I just broke half the zerk fitting in the arm. Any suggestions on how to get it out? Tried a screw extractor and no luck. Was trying to do have to remove the arm but I think I may have to and drill it out and retap the hole. Anyone know what tap to use for the zerk?

 

Thank you.

No worries, I used to be a custom auto painter back in the day.

 

ordering a set soon. are there any discount codes for tw members? are there any Canadian dealers?

 

Nope. They are already priced fair and he also includes a free gift.

Not sure about Canada.

 

yup they are priced great. gona cost over $100 extra to get them shipped to me though so i figured id check first.

 

Anyone running Dobinson coilovers with jba arms?

 

arms ordered. looks like theres gona be a 30-45 day wait time which im fine with.

 

Ooof thats a bummer, I'd drill it out and retap another one. I'd imagine it should come out pretty easy given its been covered in grease its entire life but if the extractor kit didn't work you may be stuck drilling it out... I believe it should be a m6 but might be a m8

 

Once they get installed keep an eye on the boots, they had a issue with their boots and they are set to get new ones in September to replace the current design. Mine lasted 6 months... pretty much non-existent now but JBA agreed to send me a new set of boots before the new ones come in...

 

Thanks! Yeah after many tries to extract the piece, I think I'm stuck with drilling and tapping. I have the hole plugged to keep stuff out of it and I'm waiting for the updated boots to ship out so I can remove the arm and change the boots all in one go. The new boot release date keeps getting pushed back for some reason.

 

yeah I was emailing them the other day and they sent me a post on their website that is now showing September before they are going to be fulfilled... so you may want to do it sooner than later...

In the market for a set of UCA's for my 3rd gen. Based on reading, sounds like the JBA's are riddled with annoying issues. What would people get if buying again?

 

Look at the boot

 

TC uniball or camburg uniball

 

Well I had just greased them before this happened so I don't think they will need to be greased again for a little while so if September is indeed the date, then I can wait. I just can't believe how many times this boot release date has been pushed. I'm more worried about the boots giving out than the broken zerk situation. The boots are all cracking and they are less than 4 or 5 months old.
