I need to change my u joint. I just got the replacement today and need to get this done. a couple of people have told me that you can't replace them.
Is this true? How would I have been able to buy one.

Anyway what is the easiest way to do it?
what tools do I need?
Do I have to have anything pressed out?
Things like that would be very helpful.
thanks

 

They are non replaceable. Better off getting a used/new shaft. There is a thread on how to replace the joints, but i wouldn't reccommend it. If you notice, there is no groove to hold the clips that retain the bearing caps.Most, after replacing the joints, tack weld them in. Then there is the question of shaft balance.
My .02 cents.

 

You were able to buy them because mazdatrix sells a shaft that has replaceable U-Joints on it.

 

so they can be replaced, but it isn't easy and not recommended.
great.
why didn't anyone tell me this on the other thread?
can I do it to get by until I get a new shaft? I need my car without the vibration.
