ok i just did my first gear change on my 99 ranger. it has the 7.5. ok i put a set of yukon 4.56's in it. i put new everything in it. bearings seals. i checked all my measurments with the crush sleeve, back lash, bearing preload, and the marking on the gears looked good. i got the axel back in the truck and started my break in period. for the first 200 miles i noticed no noise everything seemed good. the rear end i did notice got hot. not to the point of burning yourself but deffenetly a uncomfortable hot now they dont seem to get as hot. but now i am at about 300 miles into the break in process and i started to hear a very slight whining noise from the rear. and it is slowly geting more noticible through out speeds. and it makes it whengiving gas and when breaking. some one said it might be a pinion bearing, but i checked all my measurments so how could that be? anyone know how to check what it is?
