That was exactly what was happening with mine. Though it was still under warrentee at the time so I went in to get it fixed. It took 8 months to get me the part, but they put it in and the sound went away.rmuller said:For me it was a high pitch whine while accelerating.. thought it was the transmission.. the Tom Woods one I got cost $350 and you can do the labor yourself (or it should be less than an hour job for a mechanic) .. I think LR charges 700+ for it..
Be careful though. If you suspect its going, immediately get it checked out. If it breaks off while driving, it will "grenade" your transmission/transfercase/etc.. and then you'll be really sorry.
