Dynatrac ProSteer Ball Joints and RCV Axle Shafts?

Do the Dynatrac ProSteer joints interfere with the RCV axle shafts? It appears that the orange boot is bigger than the ears on the factory axle shafts since it doesn't fit through the knuckle. The ProSteer joints are grease-able, which means there is a grease fitting somewhere on the lower joint that would be inside the inner C.

I'd hate to spend the $$$ on ProSteer joints and lock myself out of getting the RCV shafts later on.

Thanks,
Bryan.

Not if the grease fittings are on the non threaded side of the joint like normal greasable joints

The non-threaded (cup) portion of the lower ball joint is right below the axle. That is where my concern is.

May I asked when you ordered your ball joints, cause it's been more than six weeks...

Thanks! I'm holding off on putting my new tires on until I get new ball joints in. The local shop said they couldn't get a good read on the alignment because the ball joints were too sloppy. I got 110,000 miles out of the first set of tires and ball joints, but I have some weird wear patterns that probably mean the joints have been getting loose for some time.

Thanks again,
Bryan.

We're still trying to confirm that we have clearance for the ProSteer Joint and the RCV shafts. We THINK it's OK but we're waiting on info from RCV.

We've received a partial shipment of our ProSteer ball joints and will be shipping product late this week.

I've got RCV's on my '08 Rubicon 4dr. I'd be happy to bring it by for a test fit.
I'm in Tustin. Let's make a deal! PM me!

We've got an axle coming in from RCV to allow us the check clearances. The RCV axle has larger diameter at the ball joint than a standard Rubi u-joint. The drawings we received didn't provide enough information to confirm clearance. We should have the info we need Monday or Tuesday.

Scott (DIAMOND OFFROAD) is installing sleeves, gussets, truss, PSC assist, RCVs, and ProSteer Balljoints (as soon as he receives them). You may want to get on the phone with him.

I run the RCV's and are having my Prosteer's next day aired to me by Dave at Northridge so that I can put them in Wed. According to him I found out that the Prosteer's are 3/32 taller. I put 3/32 worth of feeler gauges on top of my stock bottom joint and there's VERY little room left. There is clearance and light can get through but it's close.

A couple of thoughts: How close is too close? If they do end up rubbing (dirt/flex whatever), will the boot sort of self trim? It would appear that a little less boot would be ok but then again.....

I know that Dynatrac will know soon enough (what's the quickest way to find out the result?). Just thought I would throw my input out there.

The quickest way would have been for Dynatrac to accept my offer and let me drive over there (ten minutes away) and test fit them earlier this week. You'd know for sure right now! But sadly they declined.

3/32 taller?? Looking at the pic... it that overall length... i.e. that includes the grease zert? If so, can't it be swapped out with a low-profile zert similar to what is used on CTM u-joints?

The pictures on our site show Dodge and Ford ProSteer joints. The JK joint has the zerk on the side so it won't cause an issue.

We have an axle assembly in-house with ProSteers that is being prepped for our rig that will be heading to Easter Safari. Our test axle will be checked in that housing ASAP.

I'll post results up here immediately.

Awesome. I eagerly look forward to your report. Thanks for the speedy response as it's a bit time critical at this point.

The verdict is in and it's......maybe

The test unit we measured would not touch the ball joint but it was incredibly close. We can see that with the tolerences that are allowed with the various components that it is possible that some will contact with the ball joint. Since the ball joint end is relatively smooth and the boot is fairly thick, I would guess that the boot would self clearance. Certainly not ideal but not terrible either.

Gil will be installing a set of these on his JK very soon and should be able to provide you with 'real world' feedback and his opinion on the clearance.

I'm sorry I couldn't provide a more definitive answer.
