U Joint Replacement

Looking in the parts listing, it shows that the Spicer 5-297X
Universal Joint is a replacement for the existing Drive Shaft U-Joint.
Is this a drop in, or is there machining required? Also, that part
doesnt seem to have a zerk fitting, but Napa stocks the equivalent
size with end cap zerks and the stock zerk on the face of the joint.
If anyone could point me in the right direction, I'd be grateful.

I have 4 of the larger drive shafts in my 2 cars which have ?30mm u-
joints. (I believe there are 4 deferent styles). I replaced my u-
joints with Precision 371 which use internal clips (inside the yoke)
and the caps are ?30.2mm. From what I've seen on the Internet
Precision 371 and the SPICER 5-297X are the same size. What I did is
ground the caps to ?30mm so they would fit, I also ground the end of
the caps so the overall length would be the right size (don't
remember the size). The problem I had was the caps were rounded on
the edges so the external clips would not work correctly, they hit
in the middle not on the edges. So I machined the inside of the
yokes to receive internal clips, but in order to machine the yokes
enough to clean I had to open them up so the stock clips were not
thick enough so I had to made thicker clips.

I don't know if the SPICER 5-297X caps are rounded on the edges. If
they are not you will only need to grind the caps from ?30.2mm to
?30mm and the end of the caps to match the overall length. I have
access to machines to do all this so it didn't cost me anything to
modify. Gord told me he has the right ones for around $50.00. I
don't have the car running yet so I don't know how good all this is
going to work, I was told that I might have some vibration.

Wow, lotsa good info. Sounds like a lot of work. I gues and important item too ask is do these new joints come with grease fittings?

The Precision 371 have the grease fittings on the end caps.
The Precision 377 are the same size but don"t have grease fitings.

I used a NAPA 880 as documented in these archives from years ago.
Ground about .5mm from outside of end bearing cap with valve grinder,
added about 80/1000 shim on both sides for outside locking caps.
Grease fitting is inside the joint.

I believe Tommy (in Tampa...) took another approach as bored out the
yoke just a bit. Not sure what joint he used as all axles aren't the
same.
