When I put my 07 1500 in 4 wheel lock when I accelerate there's a rather nasty vibration. I have the lifetime drive train warranty on it and the dealer has replaced the right front CV joint and axle only because it was leaking by the seal where the axle goes in. After they replaced it, it still vibrated, so today they put in another shaft and it still vibrates. Needless to say I'm a bit pissed at this dealer right now. Anyone have any ideas as to why it vibrates in 4X4 only? I have a 2" leveling kit for like 3-4 years now.

 

Have you had your truck in 4x4 in the 3-4 years since you've had the leveling kit?

I had put a 2" level in my truck, and I noticed shortly after that it vibrates in 4x4 as well.

 

check the front drive line, especially the double cardigan joint.

 

Surprised the dealer warrantied the cv axle.

 

Many many times. Well what I'm reading here and at another Dodge Ram forum is that some do it and some don't. Strange that it's never done it before they did the front right axle.

Why? It's drive train

 

because of the leveling kit. It changes the angle of the front cv shafts, and if they wanted to be jerks about it they could void the warranty. Do a search I think there maybe a thread on some other guys having this problem too. So trucks do it some don't. Hope you get her fixed.

 

Well my dealer took the 2" leveling kit out, N/C, and it still vibrates, now what?
