I'm the 2nd owner of this previously government owned XJ that's stock minus the high pinion front axle D-30.
I've had the XJ now for about 4 years and the front knocks when turning since I bought it. It sounds like a bad c/v axle on a FWD car. It has about 79,xxx miles. I took it to multible shops including off road shops. Pulled the cover off and all is good inside. It's open axle. Some of the shops said it may be a bad axle shaft. Some shops say it's normal since it's a high pinon/reverse cut. 4-wheel drive does work. So know I'm just lost on what it may be. But in the end, all the shops just give me the
Any ideas??
Thanks.

 

did any of the shops say anything about the front axle u-joints? thats what i would check first

 

Oh ya, the outer u-joints where replaced.
