New Upper Ball joint fits loose in hole, here's my solution!

- The Upper ball joints on my Jeep Dana 30 were super loose and just dropped right into the hole. I used a punch to create raised divots around the mating surface of the new UBJ, which helped snug them up in the hole, but my main fix was to tack weld them in.
Clean up the metal on the diff and prep for welding. Do a few tack welds around the UBJ, be sure not to overheat the BJ! I did 3 tacks.
This is on a trail rig, and the last BJ's I did this to lasted for many years without failure or movement. I run 37" tires, locked F&R and the welds and ball joints held strong through lots of abuse.
I installed Spicer Upper and Lower Ball joints, the lower ball joint part # can be seen in the video.
Feel free to share your thoughts or ideas on the subject! Thanks for watching.
Sure helped me, my neighbor came to "help" and took a air sander to the inside of the bore.. upper joint it now loose... Tak weld is going to save me aloot of headaches, Thank you sir!
I had to do the same thing except I made a full 1" long bead on the inner side of the knuckle. Cooled with a soaking wet rag right after welding. So far so good after 2 years. Way I see it is if this axle fails again I'll upgrade to a 44 or buy a new used housing for $100. I also weld my axle u joint caps to prevent stretching. Stock shafts are plenty strong if you do so, they always fail because the u joint ears stretch on the yoke, not the shaft itself.
It's a good thing your ball joint has a grease fitting because the heat from the welding will probably break down the grease inside.
If you're replacing bearings every year, there's definitely something wrong. My opinion on bearings is that contamination is the biggest killer. Sand particles will especially do the job really fast. I'd do some research and find bearings with exceptional sealing. Also make sure the hub areas of your wheels are not missing dust caps or seals on both directions.
I didnt tack weld it all at once, i gave it plenty of time to cool in between. Not concerned about the grease at all, also removed the boot while welding.
Thanks for the tips on the bearings, this is a trail rig so it does see a lot of abuse and mud/silt etc. Also running 37" tires doesn't help!
Just what I was looking for. Did my ball joints and the snap ring groove was not showing even though I pressed all the way in. It was the bottom and pressed in upwards. Was thinking of tack welding them but you convinced me otherwise
