cv joints

[STERLING STINGER]

my buddys trying to tell me he has cv joints from a grand cherokee, not sure what year??

but he says he wants to put them in my mj

why... :dunno:

would they replace the "knuckles" behind my front wheels?....don't laugh :no:

are they better?

I always thought it was the other way around....That people with GC's wanted to swap the cv style axle shafts, to regular U joint style shafts.

 

If hes referring to what I think he is, then hes talking about the axle shaft ends (inside the knuckle area behind the backing plate of the caliper). Right now you should have regular U Joints on the shafts CV's are inferior IMO.

u joints are better. don't swap for cvs

thanks i won't then.....friends :shake:

Supposedly the CV axles are about equal, strength wise, to the 260 u joints. But they are higher maintenance.

this is true, the cv shaft is not really weak, but higher maintenance like stated above. rubber boots get old and crack open, grease goes everywhere. if the grease is gone too long the joint is damaged, and it is far more common to replace the whole axle shaft as an assembly than to replace the boot even, and repairing the joint itself is basically never done anymore. so take all that and compare it to replacing a spicer u joint that lasts 100k.

 

you're basically comparing replacing an entire axle shaft, to servicing a u joint.

I guess thats another benefit of having actual U joints in the shafts is you can replace them then, where as like said the CVs would be easier to just replace the entire shaft, than rebuild the joint.

cool, now it can SEEM like i know more than him when i tell him these things.....can't wait :clapping:

The ony way I could see putting in CV joints is if thats all I had and I knew it would get me fixed and going again. And I think only the ZJ CV's will work, not the WJ's, so if you do end up taking them, make sure theyre from a ZJ.
