Tried to search fo this problem but came up with nothing. When I went to install my new drive shaft ujoint this morning it was loose. What I mean is the cap was spinning in the whole instead of around the splines. I was replacing the ujoint because i noticed the old one doing the same thing.

Does this mean my driveshaft is no good since the old ujoint caps spun in the wholes and bored them out a bit? Or would buying the more expensive spicer brand joints fix the issue? I just grabbed the only ones available at advanced auto fo 10 bucks.

Soooooooo, you didn't have to press the old U-joint apart to remove it from the DS?

Did you buy the replacement based on a P/N on the old joint or by cross reference to the car?

Right, the old u-joint basically fell out once the clip were off. Bought the new one by cross reference.

To clarify a little more, I got neapco brand ujoints from advanced auto, which were the same ones that carquest had in stock. Unfortunately I took them back already and don't remember the part number.

The new parts should be press fit, check your yolks for roundness and size to see if they are out of round.

yolks aren't out of round, and they seem to measure the same as the front yolks although i'm only eyeballing it with a tap measurer. roughly 25mm

the front ujoint is a GMB brand, im thinking of ordering one and seeing if that fits.

The old u-joint bearing cup should not have fallen out when the retaining clip was removed. It should be a very tight press fit and should have been difficult to remove. Your driveshaft yoke may have been messed with or is just worn out. A salvage yard replacement driveshaft might be in order.

A tape measure wont cut it for these types of dimensions, get a cheap set of calipers (at least) at sears or horbor freight and take some measurements. Are both yolks (all 4 pcs) loose like that or just one?

all four were loose old and new

Could be the wrong parts.

could be the right parts and depending on exactly how loose you might get away with the Loctite bearing/ bushing setter compound. You will have to take accurate measurements and buy the rite compound for your gap, remember to devide the difference by two, its a circle in a circle.

Ended up buying a drive shaft from a member of the local zcar club. All is well. Now if only i can figure out where all this vibration is still coming from.
