U joint replacement
I found that when pressing in a new u joint, that the shaft on the new u-joint tends to wander off center when pressing in one side and without a cap on the other side. This tended to scive the inner yoke bore.
To get around this, I took one of the old bearing caps, chucked it in a lathe and ground down the OD until it was a slide fit. Cleaned out the insides and put new grease to keep the old needles in place. I used this to keep the new u joint in line while pressing the first cap together. This worked a lot better.
I used a 20 ton press rather than a vice. For a vice you need at least a 5 inch jaw opening. Also with a vice, you need to keep the socket in line and keep them from falling out while your lineing things up. In a press, you are working vertically, so you don't have to worry about things falling apart.
Also, I landed up just cutting out the old ones (as Gerry suggested) rather than trying to press them out. There is a lot of force required to get them out after 30 yrs
Just thought I'd pass along my experience from this wkends job.
