Spindle/ballJoint fitment issue

First post... but not new to reading the endless knowledge on this site.

I have upgraded to the UMI Performance stage 4 suspension kit for my 1966 Chevelle. I purchased the front power disc brake conversion from The Right Stuff with stock height spindles.

The spindle doesn't want to fit on to the upper ball joint. The lower ballpoint seems more accepting but still a tight fit. I've used heat in the past to get them to slip on, but that was with stock control arms on cars that were not this important to me. I dropped a pretty penny on this suspension and I'm not trying to mess anything up by putting a torch to it. Does anyone have any suggestions as to what I should/can do?

Re: Spindle/ballJoint fitment issue

not sure what you're doing here. you mean the tapered studs of the balljoints won't fit in the tapered holes in the spindles? Please clarify. get you get pics oif the exact area in question?

I'm putting the spindles on the control arms. In the close up picture you can see how the top ball joint is not seated. The ball joint is too tight and won't fit on the spindle.

Re: Spindle/ballJoint fitment issue

With no weight on the front of the car, you're probably fighting the springs. Might need to use a spring compressor, looks like the stud and the spindle aren't quite aligned properly in the pic. With no engine, should only take a couple minutes to remove the upper control arm from the frame, making it easy to check if the ball joint stud fits in the spindle or not.

Re: Spindle/ballJoint fitment issue

Looks to me like there is a difference in the taper between the spindle and the ball joint...

Re: Spindle/ballJoint fitment issue

I've never seen one that far off unless there were mis-match parts. UMI is you best bet.

You could unbolt the ball joint from the control arm, try it in the spindle by itself. A few minutes to try this.

Re: Spindle/ballJoint fitment issue

Are these tall/extended length BJs? If so, they will look off. What matters is if you are able to seat the BJ into the spindle and get the castle nut down far enough to get the cotter pin in.

Re: Spindle/ballJoint fitment issue

Ok I may have jumped the gun on this one yesterday. It was a long day of stripping and painting the frame before assembly. Went to the shop during lunch today and fit the original upper control arm to the ball joint and it slid right on. So I knew the spindle was good.
I talked to Zack today at UMI Performance and they confirmed what GenPac just wrote. Attached are pictures of the way they are sitting with the taller ball joint. The boot still sits about 1/2" higher off the spindle which was most of my initial concern, but I was told this is correct.

Thanks for everyone's quick attention. Planning to start a small build thread on here. Slow progress is still progress. haha.

If you don't like the way it looks with the exposed BJ stud, I took some 1" diameter copper tubing and sliced about 1/2" length off and used it as a spacer between the Spindle and the BJ boot. It looks better and the boot stays put and keeps the grease in...

Won't the copper tube cut the BJ boot as the ball joint goes through the suspension movements ?Painting the exposed metal may be a better solution.

Re: Spindle/ballJoint fitment issue

The tall ball joints from Howe have a piece of rubber tubing on them that compresses just a little bit during assembly. I think that may be a workable solution for yours to keep the boots in place.

I've had them this way for 4 years. I would guess it depends on the quality /thickness of boot you're using. To each their own.

I was just thinking when I cut apiece of copper tubing with a tubing cutter the sharp edge it leaves and envisioning it cutting into the BJ boots.Even after you file the pipe it's still a little sharp,but whatever works for you is cool with me.
