Many use one or none today.Some use one w/a rubber coupler at the rear,and yes,
IRS w/ a basically fixed diff minimizes this.Ask warren johnson and other pro stockers why
they switched to CV's instead of u-joints back in the 80's/early 90's. And who says cars
don't still do that today?I work these freakin junks every day, and many have the same
characteristic, and are instructed to tell the cust. it is normal. u-joints actually travel in
a tiny elipse at it's center.But cheer up sunshine,at almost half the century mark the one
thing I know for sure is,I learn something new all the time,and I'm happy to.
Oh, look under these new cars and check out the huge chunks of metal&rubber hanging
off of the diffs,exhausts,and tranny mounts,gee wonder what those are for?
