1999 Land Rover Range Rover Question
when you press the gas pedal hard going up a hill or sometimes on flat ground it makes a clump clump sound coming from the front end. A while back we where going to pull off our tractor and hooked up the range rover and put in drive and the truck was like it didn't grab and it was just a long clump clump clump clump
Any idea what could be wore out or what could cause this
We are still driving this daily and would like to fix this problem
Any help appreciated

 

also does any body have a break down of the front end
