i bought a 6" suspension lift from tough country. Before I started the install i went through my truck and replaced any thing that need to be u joints etc. after install I'm getting a front drive shaft growl that wan't there before. Is this just because my front drive shaft is piched at such a steep angle. and is there anything i can do about it. thanks

 

I'm no expert on suspensions, but I know on the rear you can loosen the U-bolts and rotate the diff and aim it up. There has to be some way to do a similar thing in the front...anyone else able to back me up?

BTW, I've been shoppin around for a 5-7" lift myself, how ya like the Tuff Country setup?

 

Just another thought, I've seen some kits that come with a shim for the transfer case to help the angles, this may help out

 

If the noise is being caused by excessive drive shaft angle, the easiest fix would probably be to get a custom shaft built by a company such as High angle driveline or Tom Woods. They both build shafts that will accomodate severe (sp?) angles reliably, and also offer very strong options such as 1450 CV joints and such. I know there is also a u-joint out there with offset trunions made to accomodate excessive drive angles, but I dont think it is meant for use other than slow off road stuff (10 mph?), I think its made by Tom Woods.

As far as the diff rotation idea. To accomplish that you would have to cut the spring perch's off the axle tubes, rotate the axle as desired, and then when everything is perfect and properly aligned, the perches would have to be re-welded on. A pretty easy operation on the rear axle with the proper tools and know-how. Degree shims are also availabe which install between the axle and leaf pack or block and will change your pinion angle the same amount as the shim you install, they are available in varying degree's. The front axle gets MUCH more complicated! The only way to really do it correctly would be to pull your C's off the ends of the alxe tubes and reinstall with pinion angled the way you want it, while still maintaining factory alignment angles. And on the dodge front axle, im sure you would also have to re-locate spring buckets and trailing arm mounts to maintain factory positioning. This would all require lots of specialty equipment, tools, and know how to accomplish and keep the truck safe and driveable! As far as lowering the t-case, that would probably only help with the rear driveline angle, and would possibly make the front angle worse! Also, keep in mind that by dropping the t-case you will also be angleing the engine, trans and t-case as a whole which could cause other troubles as well!

Sorry for the long post, but hopefully some of it will help you in your search for a fix.

 

ya i just didn't expect this because it is only a 6 inch lift the t-case side of the drive shaft has a 2 u-joint setup i was thinking if you could also put the same set up on the diff side that it might help.

 

6" lifts will will cause all kinds of problems that need to be corrected on most vehicles. I put a 6" in my old super duty, and I had to get a new shaft made by high angle driveline. Jesse at high angle said he had never heard of it, but my stock shaft was not working for me. You cannot run a CV on both ends of a shaft as far as I know, I think the shaft would just flop around.

One thing you might check, is your clearances on your CV. Stock shafts are not made to accomodate very high angles at all, so it is possible that you have interferance up there. If there is you could clearance the ears a bit with an angle grinder, but I wouldnt recomend removing too much meat.

 

cool ya ill check it out

 

Some 6" kits come with a 1" trans. lowering mount... you could get one of those

 

i did a couple searchs, now correct me if im wrong but does it matter the spot the drive shaft goes back in. what i mean is there two spots the driveshaft fits so if it's out 180 degrees would this make nosie

 

Have you contacted Tough Country about this. These lifts are engineered to work flawlessly.

 

Common issue over 4.5"

Front driveshaft is too steep. Easy fix. Get a transfer case reindexing ring and it'll work like a charm.

Rear driveshaft issues get a small spacer under the carier bearing as noted.
