Hey guys. Just wanted to see if anyone has had this issue, and maybe a remedy.
I’m replacing the U Joints in my old propeller driveshaft. I’ve got a good C shaped bearing press, impact driver, etc. Put some light grease in the old holes and got the rear side done with zero issues.
The holes on the front end are pretty out-of-round, and the caps just won’t go in straight, even hand cranking the press. The caps keep diving off at an angle and just won’t track. Tried with the impact driver going slow and they got to about halfway and stopped… then the yoke started bending. Uggg.
I think the driveshaft is shot. With out of round holes I just can’t press anything in straight. And now the caps are stuck as you see below.
Is it time for a new driveshaft?

Have you tried an hydraulic press? They don’t look terribly out of shape. If in your press you can still bend it then yes a new yoke is needed.

No hydraulic press, just a large hand operated press where we used an impact gun or hand cranked the screw to press the caps. Unfortunately, no matter how we attempted, the caps would jam and then the whole yoke ear assembly would begin to compress and get further misshaped. The other side went in beautifully, straight, perfect with no caps tracking oddly.
I just heard that we have a really good axle and driveshaft shop in town that rebuilds, welds, and balances driveshafts. I may try them and see what my options are before buying a new driveshaft.

I believe a new yoke is in order.
Take it in to a reputable shop and let them guide you.

Ron has NOS small end threaded seal yokes for 50 bucks, Wonder what a drive shaft shop will charge you? Just get a used shaft that is good and go from there.
