Ok I am fairly new at this site but I have a 1999 Dodge Ram lifted 5’’ lift and there is this annoying problem. There is this knocking sound almost like a tire rubbing but its not the tires and it sounds like it is coming from my front end. I’ve check all bolts, u-joints, and shocks and everything seems to be normal. It only makes the sound at real low speeds 5-15 Mph most of the time with no load on drive system. But if I do have a load on the system going about 5-15 Mph it does it when I hit bumps. Can anyone help me with this here problem, Thanks

 

When you hit bumps? This throwing this out there but have you checked your control arm bushings? If you have a lift though I imagine they're pretty good quality.

 

Yes, the lift is Skyjacker and I had the 4 Wheel parts Company put it on.

 

how steep is your drive shaft angle? could be a bad u-joint in there or binding (i dont have 5 in of lift so i dont know steep it can go befor you run into problems)

 

yeah i think its just a bad angle.. when you get up over 15mph the u-joint is just spinning so quick you cant even hear or feel it anymore.

 

I really appriciate the responses. Sounds like that could be the problem and I will look into it more. Thank you again!

 

Well, I didn't really get where it was comin' from. Maybe I'm just a bad reader, but you said from the fender? Or was it the motor? Is it constant at the same pace or rapid? I need to know this kinda stuff. But from the posts, I'd agree with 20dodgeram01.
