I just ran this procedure yesterday, probably my fourth or fifth time. It was the first time I had experienced the tab bending locking up the tapered rollers as you described. I disassembled the washer stack up to ensure proper orientation, and assembled taking care not to torque the washer stack during bending. I don’t know what changed, but I assume the preload on the needle rollers was not adequate, allowing them to bind.

Just like greasing the needle rollers to capture them to the peg, the ball races should be greased to capture the ball bearings as you slide the collar and clip down the shaft.

I acquired 1500w (yes, you read that correctly) gear oil, and this spare box of mine is absolutely gorgeous in workbench tactile feel. It will be in my car by next week, and I’ll let y’all know how it does over the next few months because...

Wolfgang International in Redding, CA has a machinist who bores out the boxes (as long as the part number ends in F. No E boxes allowed...) and installs silica-bronze bushings for the output shaft, so maybe I’ll once again take a dirt road without clunking. It’s not cheap, but the bushings could be replaced over the life of the car, and this could extend our early bay originality well into the next century with careful maintenance and driving.

Robbie,

Did you have Wolfgang install the bushing in your box? If so, what was the cost if you just shipped the housing?

How not cheap?

Wolfgang rebuilt boxes are $300 plus a $200 refundable core charge. I am dropping my box she’ll and pitman shaft off in person and having them complete the machine work when I drive through in two weeks. I don’t need them to do the rest of the box rebuild, as I have fresh seals and my “by feel” adjustment has left no additional wear in the box after four years of hard driving.

Hopefully it will be less than $300, but at this point I’d just like the clunk to stop.

I'd be curious how it goes after the installation of this bushing and then your reassembly. My box is still pretty tight. I disassembled it and it looked great inside with no obvious wear. I replaced the seals, cleaned and repainted it. Colin did his magic on the final adjustment. It still has a bit of a clunk to it.

Hello,

I'm rebuilding a box very similar to yours, but the bearings are missing. Do you know where I can purchase a re-build kit that comes with seals and bearings?

No such convenient luck.
You may need to match up dimensions and order bearings based on size. The seals seem readily available and we have the sizes already posted here.

Thanks for the response.

Update :
I went to my local bearing distributor and picked up the required seals, but they could not get a bearing that fits at the bottom of the worm gear.
Do you have a part number or any idea where I could find one?

I do not, but the internet is a vast emporium of part numbers.

What has indicted the bearing that is already there? Looseness? It is preloaded by your shimming and adjustments, so only damaged races or balls/rollers would require replacing it.

I have had no such luck finding part numbers... I'll keep searching.
The bearing races are pitted from corrosion, and balls missing.
I will post in this forum if I come across a part number or alternate solution.

Thanks!
