Hello everyone- Recently I've been feeling and hearing a slight vibration In the Rover. Cole European has been saying the rear differential is going out. At work the other day I jacked it up and tugged on the wheels to see if it was a wheel bearing assembly ( I had my front right wheel bearing go out and replaced ) and there was no play at all. Atlantic British wants $2,900 for a new one http://www.roverpart...Parts/LR009444G , Rover Land Parts wants $2,000 for a refurbished one http://www.roverlandparts.com/2005-2009-lr3-differential-assembly-limited-slip---rear.aspx and I believe its about $5,000 at the dealer for a new one installed. So my question is what to do? I have a HD so I have a electronic locking rear diff. Should I just get a replacement, should I get a non locking and buy a ARB air locker for it ( I want to get a ARB front locker anyway ) should I try and rebuild it? or just take it to a shop and have them do everything? It's my daily driver right now and I have 171,000 miles on it. Does anyone even want to help install it cause I have no idea what I'm doing. Thanks for the help! I'm just kind of at a loss for what to do, it's a big fix.
