Repairing the UJ on driveshaft

[xLibelle]

Anyone have experiance doing this on their own?
I've found suppliers and shops and I feel like this can be a DIY thing.
Anybody?

On the same subject, BMP sells a driveshaft that has been machined to accept standard, removable universal joints. Anyone know what exactly they do so I can replicate it? Will make it much easier and cheaper to rebuild.

$500 though so I would rather do it myself.

The typical life of a drive shaft is well in excess of 100k, so having one with field replaceable u-joints is of dubious benefit. The OE drive shaft has the u-joints staked or welded in, which makes field replacement almost impossible. And then there's the necessity to balance the drive shaft after replacing the u-joints. Just get a rebuilt drive shaft and forget about it for a long time.

I just replaced mine. The U-joints were very hard to move at the back and the new driveshaft is like butter. The original one had 198,000 miles on it and it's one of those things that sneaks up on you; you just don't notice the vibrations get worse and you live with it.

Not really something that a DIY can do correctly.

Takes some machine work because the OE ones are "permanently staked" and the replacements need retainers (requires cutting a grove inside of the cap bores in the yoke) and they never last as long as the OE method even when done right.
