Hey guys i get a clunk in the front end on the driver side. It only happens when i am in 4wd and on a incline. It doestn't happen downhill or when i am flat. Only when i gas it Its real bad in 4 low because of the added torque it really pops. What could this be? Sorry i have a 4.5 inch RC lift 31's and i have the steering box reinforcement plate. stock track bar.

 

Stretched transfer case chain, maybe? Have you tried having someone drive the Jeep up an incline while in 4LO while you stood outside to try and locate the source?

 

not yet that is a good idea. I will do that when it stops raining.
