loud whining from rear end d44
98 Xj 145k 6.5" with SYE d44 4.88 gears with limited slip. I have had this problem since I've bought it 8months ago. PO stated he's tried fixing it with outer bearings when he realized it was from the inside. Possible pinion bearing. He bought the Xj modified too so it could be just years of abuse that has caused this. From 10mph till about 40 45mph a loud almost deafening whine come from the rear end and it continues around 20mph as i slow down. Any type of coasting down hill it quiets up but with even a tap to the gas petal itll whine. Hopefully someone can tell me "yeah that's exactly what it is!" Because I don't really have the money to replace a whole lot. I guess the first step would be pull the cover clean and refill. Just hope I'm not looking at replacing a rear end now. Those gears are not cheap!
