Default U-joint replacement

Starting to get a nasty clunk from the rear, and I'm pretty sure it's the u-joint going out (least, not an expensive part to swap to see if it makes a difference). Summit only has 2, a Precision and a Lakewood. Are there any other specific ones to go with, instead of the Lakewood? Also, how hard would this be to do at home, as opposed to having a shop do it?

Normally it only happens when I'm rolling forward slowly in 1st gear with very slight throttle, and I push the clutch in quickly, and I get a clunk and a physical thunk from the rear of the car. Doesn't always happen. It also occasionally clunks in a situation like going slowly through a parking lot in 2nd gear - I'll get a series of clunks and jerks, like engine surge but without the jumping rpms, if I'm only lightly on the throttle to keep it moving forward, but they go away as soon as I give it gas...almost like there's slack in the drivetrain until it gets spinning faster. This was occuring before my 4.10s went in, but I think they only exacerbated the problem, as well as the new clutch - Id'd assume there's a hell of a lot more shock occuring at shifts with the 4.10s and a clutch that isn't slipping like a fat girl on ice.

I get that noise too. I think its just the drivetrain taking up the slack. U-joints are probably fine unless you have some kind of bad vibration.

I'm getting a bit of that, although it might just be because it's been over a year since I had my tires balanced, and the Fuzions didn't keep a whole lot of tread on them. Got a whole list of little **** that needs done to the car to catch up on.

For $30, I wouldn't mind trying it to see what'd happen, if it's something I can do in the garage without needing a machine shop to do anything. Just from a quick peek under the rear, I'm not exactly sure how it comes out or goes in, but I couldn't really get up close without the car on ramps.

On a side note, I can't wait to get rid of this piece of **** 10 bolt and swap a 9" in under there.

I'm pretty sure you need a press to do it. And a torch to heat up that plastic junk. The steel driveshafts you can beat them out but obviously aluminum you have to be careful with and use a press. I did truck (steel) driveshafts all the time at dodge but when it came time for my u-joints I just dropped it off and let someone else do it.

Like I said that clunk is pretty normal...and just becomes more obvious with a more grabby clutch like your tex or my spec 2.

Its really not that tough, but like keliente says, youll need a torch. I used a pipe soldering torch and heated the yoke up on all sides till it started smoking a lot, then I punched them out with an old socket extention and a lump hammer.

That's how it's done!
