Well I need new ball joints. An alignment couldn’t really get it all together, plus a have very distinct popping with every movement.

My local Jeep shop gave me a quote for parts and labor for $1K, but no way, I’m confident I can do it. They were going to use Teraflex ball joints. From my knowledge and experience it’s a great company, but I keep reading about Spicer.
My main concern is the shop was going to use knurled ball joints and the Spicer ones I’m looking at don’t seem to be knurled.

Thoughts?

Thanks for the info. After further research I found that knurled ball joints should only be used as an absolute last resort.

The Spicer ball joints you bought were the exact same ones I just purchased. Fingers crossed it all works out

Knurled is only used/needed if the ball joint seating surfaces have been damaged.
 
When taking out the old ball joints use the press, then whack the inner C with a BFH, then press, whack, press whack. The OTC ball joint tool works well.

OP,
Do you know if knurled bjs have already been installed? I will always opt for spicer if knurled ones haven't already been installed. If they have then your choice is easy.

I do not know. I just bought the Jeep a few months ago. Is there a way to tell?
 
Or, dimple the body of the Spicer, use some 609 and go have fun.

I did this.

Just did mine. The lower were pretty hard to remove. I soaked with 50/50 ATF/acetone. I put the ball joint tool on it and left it for a while tightened. Then hit the top of the threaded rod in the ball joint tool with a BFH and it finally broke loose.

Next time hit the C, not the threaded rod. The C is a bit stronger and wont deform to the point you can't use it!

Yeah I did that too, but it wouldn't budge that way. I didn't have to hit the rod that hard — nowhere near hard enough to bend it....
 
I did mine a few months ago. I didn't even play-I hit all of them with the propane torch first. After everything cooled, I hit it with Liquid Wrench. Also, I used a piece of PVC pipe over the threads of my press tool to protect the smooth surfaces while doing the lower ball joints. Hub removal was the most difficult part, in my case. They did not want to let go.

anti-sieze on the mating lip any time I have to remove the bearing has made my life a lot easier.

I practically painted everything with anti-seize except where loctite was recommended. The next time should be much more reasonable.
 
What do you mean by this?

The press gets torqued to remove the old ball joints from the inner C. Whacking the end of the C on the axle (where the lower and upper ball joints are located) relieves that pressure the ball joints are seeing and the press doesn't need as much torque to remove the ball joints.
