Just had my truck leveled today looks awesome but vibrating like crazy in 4x4 when Im going from 0-60, whats the fix?, is there a fix, help!!

 

Did you have the alignment done right after?

 

Dont drive 60 mph in 4 wheel drive? Why would you do that unless you were drag racing with a Diesel?

 

Going in for an alignment tomm morning, will this fix it? The guy who installed told me not to align it til i do 150miles first

 

I hate to say it, but welcome to the shudder club. Mine has been like that since November. The dealer replaced the front drive shaft, rebalanced the tires etc etc... nothing worked. After a ton of research I've decided that it might be related to the inner CV joint angle being too steep. What I read is that the inner CV joints used on the '06-'08 RAM 1500's can only handle up to 15 degrees of pinion angle. The level kit puts it over that as far as I can tell.

The strange thing is, my buddy has the same truck, same level kit, but no shudders.

I am going to call KORE tomorrow and pick up their high angle inner CV joint kit for the 1500 and see if that helps. I have my fingers crossed because other than the shudder, I love my truck.

 

I've heard tell that they went to a different manufacturer and a thinner shaft CV necessary for the coil over front end. But have NEVER gotten anyone to confirm. I didn't like tires over 35's and lifts over 4" of suspension lift on the '02-'05 torsion fronts, I don't know what to tell people on the 06+ trucks.

It's be nice to get a confirmation on this, but I don't think it's something they'd "advertise".

And Subzeroti, don't jump to any conclusions till you have the alignment done, it's gonna vibrate till then, regardless...

 

what kit do you have?

 

yes, definitely get the alignment. I heard that they switched to some crappy *** Chinese made ones. I hate that it's so hit and miss with the '06-'08's. I'm really hoping the KORE kit works. I'll be sure to let everyone know my results either way.

I originally had a HBS 2.5" kit, and replaced it with a 2" TGC kit. Both shudder, but the 2" shudders a bit less.

 

oh so you swapped a 2.5" for a 2" and not much change?? If i cant figure mine out im just gonna pull it out

 

That 06 shudder is a common problem after leveling. Lots of guys have had problems with it. They say 2" is probably safe, but any higher, there could be problems. Something to do with the driveshaft angle. Good luck with your problem.
