: CV joint, mount at tranny or axle end??

I lifted my S-10 and now the driveshaft works, but too short for comfort. I can get it shortened for $80, and can get a CV joint at a local junkyard for probably $20. The local shops want $220 for a new steel driveshaft, and basicly I'm being cheap, and the extra flex out of the driveshaft couldn't hurt. And conversion u-joints are cheap too.

Also, will i get more vibration? I'm assuming I should get them balanced together?? My pinion and tranny angles are parrallel now, will a CV joint change that??
Thanks

Hope you have good nomex.... or really thick skin. May God have mercy on your soul.

The CV goes on the tranny end

If the angles are parallel you shouldn't need a cv driveshaft. The cv is supposed to reduce the vibrations caused by angles that are not parallel. It sounds like you just need to have your current driveshaft lengthened or go with the hihangle driveline rockcrawler. I love mine. Look for a reply by onetoncv, he'll have all the answers for ya.

sorry bob, you lost me on the nomex, thick skin comment.

My understanding of the purpose of the CV joint was to give additional flex to a drive line so you don't bind the two exsisting u joints. Shims or perch relocation should be used to correct for wrong angles.

I was looking at a different CV joint I had in the garage, and I would have to have one part of the joint welded to the driveshaft, which probably won't work because I have an aluminum driveshaft. I doubt there are any aluminum CV joints.

Sometime being cheap doesn't pay.

You fawking newbie idiot. Someone actually allowed you to buy a 4wd vehicle without knowing........:flipoff2:

I think he was saying someone might chime in with one of those type responses. CV always goes at tranny end. Like wilson said, a CV is to make up for tranny and diff offset angles not increased articulation although in some cases it helps. No need to go buy some expensive shaft just have yours modded by a competent shop. Since your pinion and tranny angles are close then you should NOT run a CV.

I was going through the local junkyard, and saw numerous factory fords (70's lincolns, crown vics, and such) w/cv's at the rear axle end. Soooo..... If the factory set the pinion angles right in the first place, on a hooptie land yacht that considers a speed bump articulation, then why the hell did they put them on??? Decoration?? Bunch of them sitting around, wanted to used them up??

I would never consider that on a 4x4 though.:rolleyes:

Crawl under a Cadi and see CVs on both ends..:rolleyes: Still can't figure why this works.

Yeah no kidding. I have a Cadi shaft in my backyard waiting to be chopped up to make square drivelines.

CVs at both ends work fine. The advantage would be you could keep the dif and t case in line (for castor purposes, to avoid running mods other than lift leaf springs whatever) and still run major lift.
