Wink JBA upper control arms

I finally bit the bullet, my JBA upper control arms arrived today (thanks Stew from Murchison's).

I have all the front strut parts except new springs (but I think I will buy some new ones), lower control arms were replaced about 18 months ago so all the front suspension is getting freshened up so I can finally do the Cape trip I have been longing for since well forever.

For all those that have fitted JBA UCA's what tricks did you use to make the install easier?
I will have the struts out and be doing the job all at once so any tips would be nice.

Hardest part for me was compressing the 2 inch OME springs enough to fit the shock struts.Think I reversed the upper arm bolts so arms could be removed easier next time.Of course you have to move coolant tank to one side etc. I think my greasable upper ball joints supplied with the JBAs have gone.These originals are not really sealed that well against water ,dust ingress etc.I think the later ones may be better.

Yeah, I'd say jump in and remove the stuff above them in the engine bay, makes it a lot easier. Definitely agree that compressing the springs was the main PITA, I found all the bolts came out reasonably well which was a nice change.

Mine have the new rebuildable ball joint, I have some concern about the rubber boot keeping the dust and dirt out so I may run a small bead of sealant 95% the way around the cup as a precaution, either way I will be sure it seals well.


I remember fitting the springs to the struts all those years ago, I will definitely be using a proper strut compressor or get a clam shell spring compressor for that job.

Ball joints look completely different to mine
Keep them greased up, & wipe away the excess
My install post has minimal details

PITA for me was accessing the inner bolts
I removed the plastic inner guard liner on driver's side
@08crd recommended turning rear bolts around for next time

Loosen the upper ball joint nut, spray liberally with lube
Let suspension drop to full extension
Beat the shite out of the steering knuckle on the flat spot in front of ball joint.
There was enough spring pressure in mine to separate the joint

After reassembly get a wheel alignment
Allow two beers per side

I think it may take me 3 or 4 cold ones per side

The ball joint sealing is definitely a weak point.I have been away for 3 weeks ,greased well before I went , went through some heavy rain.Greased again this morning and some water came out nearside.I note JBA now advertises the new style ones on his site.They still only appear to seal by the rubber pressing on the arm and spacer.Trouble is under full suspension movement the rubbers distort a bit.

Had a pro put mine in, along with crd stu ome yellow poles and black coils. Additionally have bags in the rear coils. Great comfort on long trips and handles great, even up and over 150kmh. Down the centre. Haven’t looked back.

I put mine in a couple of months ago.

Same issue with the rubber not completely sealing the joint. But keeping grease up to it should help.

I removed both inner fender liners for MUCH easier access to the inner bolts, but think I now have a squeak coming from that area after some deep muddy water holes.

Cheers
Ben
