CV joint swapping...
 

Hello everyone:

I have read archives from several sites regarding swapping CV joints, keeping the half shaft orientation the same. My question is - I have had my engine/trans out and am getting ready to re-install, I am getting ready to repack the trans side CV's and was wondering if I could swap just the 2 trans side CV's. Wouldn't this do the same thing as swapping each side's CV,s, except only doing the trans side ones ??

Thanks for any input...

If I understand your question correctly, then the answeris YES. I am assured they can be switched with excellent result. I suspect you are asking whether the two "inboard" joints (the ones bolted to the drive flanges coming out of the tranny) can be switched. Yes, they can.

If this is not your question, then consider this: the point is to switch them so that the engine's power is pushing them the opposite direction from before. the horsepower then bears on previously unused (except in deceleration) race surfaces.

I guess I don't understand why you want to change only two of the four CV-joints rotation ... I always swap ends on each side of the car, always keeping the left axle on the left side of the car, changing inboard to outboard ends every time I pack the joints every other year. It probably doesn't make much difference whether you swap or not ... the main thing is NOT neglecting the joint's lubricant or boots!!! If you find lubricant all over the place and a cracked boot, you can bet that particular CV-joint has already been damaged, maybe fixable with new ball bearings, or maybe not ... if the races have been scored, scratched, pitted, etc.
