question about u-joint
I was told that the u-joint on a 87 base model can not be replaced by its self, and that the whole drive shaft would have to be replaced. I just want to know can I just replace the u-joint so I don't have to spend a couple hundred on a whole new drive shaft. I know that mazdatrix only sells aftermarket u-joints that only fit their aftermarket driveshafts. But advance auto parts sell the u-joint but I don't want to buy the part and have the car in the air and find out that I can't remove the factory u-joint. plus I had other work that I had to do and i wanted to do it all at once. Please help and thanks

no, the u-joints canNOT be replaced on the stock driveshaft. you can get a 87 n/a driveshaft for like $20 used and in good condition. I actually got one from a friend for free that would in excellent condition. do some searching and you can find a good one for cheap.

Yes, the factory design is that the U-joints are not replaceable.
There are a couple people who have bent the horse shoe joints enough to replace the U-joint in it, but I am unware of how that worked in the long term.

These guys have a replacement.

You have to grind off the burr that holds the old ones.
A Dremmel works good for that.
They have instructions.
I used a bench vise to press out the old joints.

Rockford driveline Part number 430-10A. You need two. it will cost around $55 bux with shipping
Both the previous posters techniques for changing will work.......I suggest the drimmel tecnique. Grind it smooth so the new ones go in smoothly.
On the west coast there is Arizona Driveline that has the same part number for the same price.
Why can't we get ONE of the u-joint threads as a sticky or in the faq or in the archives.
Of the 28 things that go wrong on an FC this one would be top 10.

the u-joint acually works fine its the damn squeaking thats bothering me. Yeah they probably do last a long time but my diff mount broke a while back and I drove on it while waiting for the new one which took like 5 weeks. I tool it easy most of the times but I found myself racing against pr!cks in hondas and doing the occasional drift so it was my fault. But I'll probably just go buy the whole drive shaft, Mazdatrix has a new aluminum one and u can change out the u-joint. THanks for all of your help.

The dealer told me the same thing and so did several other folks. I wound up taking my driveshaft down to a local drive shaft shop. As soon as I walked through the door the guy was like oh you've those "un-replaceable" u-joints. No problem! He had the new u-joints ordered and installed in 2 days. The cool part is the new U-joints had grease zerks on them. If you go to a good quality drive shaft shop they should be able to do it no problem. BTW, I think it was $105. I can't remember how much a new "propeller shaft" was but I want to say it was like 400 bucks!!!! I like my fix much better!!!!!
