After fixing Axle Leak.....
Some of you may recall my earlier post about having a 
hard
time getting the axle seal to stop leaking on my '76 f150 4x4.
As Lanero suggested, I had the shop replace the seal along with replacing the bearing and crush ring.
My question is this...Now, when I'm coming to a stop and push on the brakes, I hear a "howling" sound (rather low pitched, almost sounds like tire whine). Am I missing something here? The brakes are new, and I've double checked them to ensure I installed them correctly.
Is there an adjustment in the rear end I have to make?
Thanks!

the shop might not have double checked backlashing of the gears and just slapped a seal in it and crush collar but never double checked the lashing or didn't do enough preload on the bearings or which is really the guy working in the shop on your truck replaced your crush collar and seal and took an impact and put your yoke on to crush the collar and never checked preload on your axle and cranked the bearings to tight which is very common. doing a crush collar with an impact is a very touchy thing to do. My suggestion would be take it back and make sure the guy does it right not just blast the yoke on with the impact without double checking backlash and end play in the yoke. You need to have .008-.0015 of backlash in the gears for heat expansion on the Ford 8.8" 9.0" 10.25" rear axles the preload for your pinion bearings for all the axles useing your old bearings should be 8-14 INCH POUNDS not foot pounds according to factory specs
You paid them and they didn't do it right take it back I would suggest
before it really gets bad and the all the bearings are shot

[updated:LAST EDITED ON 27-Mar-02 AT 01:11 PM (EST)]I am the one who re-installed the axles, but they did the crush ring, bearing, and seal removal/replacement. When reinstalling, it seemed
a little tight, but not too bad. The howling didn't occur right away, and now it seems to flucuate, but definately does it more after I'm driving a while but only when I brake.. now I'm concerned..sounds like I need to pull the pumpkin and make some adjustments? I have no clue on that... Maybe what I'm calling a crush ring isn't; I'm trying to describe the steel doughnut that's pressed on the axle after the bearing and seal are installed and it "floats" in the rear end housing. Is this right?
From your user name it sounds like your from AZ; me too. Would you know of a reputable shop that could do this?
Thanks

the crush collar goes between the taper bearings on the pinion shaft you crush it for proper preload with the yoke nut. As for reputable shops here in AZ I couldn't tell ya I do all my work myself.
the donut collar that presses on the axle are you talking about the one near the outer axle that holds the bearing to the outside race on the axle shaft that would just be a bearing retainer that one should just be touching the axle bearing

EUREKA!!! I understand now.. Thanks for the clarification on the
difference between the 2 rings.
Any idea's on what the noise I'm hearing is caused from? I didn't notice it before I replaced the axle seals...
Thanks again

If your brake drums had not been off for some time it is common for them to be rusted on so hard that a puller is used to get them off and alot of the time they will bend a bit before coming loose. One may be wobbling enough to make noise when braking . I've straightened them by simply putting them on a flat surface (I use a flat tree stump) and straighten them with a sledge hammer. This could possibly be your problem.
