hey fellas i have a 2001 cherokee sport aw4 np231 with a grand cherokee fornt lp30 and a ford 8.8 in the rear.
i have a grinding noise that comes under hard accellerations in first or reverse. it only happens sometimes. im fairly certain that the unit bearings are fine although i did notice some black grease on the back sides of them when i did the gc30 swap recently. the xj only has 55,000 on it and the trany has been well maintained. also the sound seems to be rotational.
