You don't need to remove the axel. Just remove the wheels and then the brake drums. There are two bolts that hold the wheel cylinder in place. Before you try to remove the wheel cylinder you must disconnect the hydraulic line coming in to the cylinder. After you change the cylinders you will need to bleed the lines until all air is purged from the system. As you bleed the lines remember to keep the master cylinder reservoir full so you don't introduce more air into the system. If when you are done the brake light is on you will need to bleed the proportioning valve also until the light goes out. Remember brake fluid will ruin paint! Do not get it on any surface you don't want damaged.

If my memory serves me correct, I believe you need a special socket to do that. It's a long diameter round socket with small tabs around it.

How do I get the wheel bearings off of a f250 7.3 1990 4x4 manual hubs?

Jack up the axle and secure it. Remove the rim and tire. Remove the caliper. Remove the manual hub cover (the part that engages the hub) by removing the small Allen head bolts.Remove the big snap ring/"C" ring along the outer edge. Screw 2 of the Allen head locking hub bolts back in and use them to pull the lock out. Next is a large nut that has four indentations in it. There's a special socket 4x4 socket available for around $15 that fits right in there. Remove that nut and the whole rotor and hub will slide off. Because the socket doesn't scar it like tapping it around with a small hammer and blunt chisel.

Four wheel drive not engaging

Check the front wheel bearings for play and also while the wheel is off the ground lock the front hubs, grab the axle behind the wheel and see if it is engaged. If not then you will need to take the hub apart and find out what is broken.

Since yours is front wheel drive, simply detach the diff from the chassis. Open up the diff which consists of two halves.The transmission axe has a spider bearing assembly held by four bolts. On opening the top half of the diff, you will be able to separate the rear axle shaft.......sodeep

Just replaced master cylinder on 1990 aerostar and bled the brakes, still the pedal goes to floor and i have no brakes

Did you bench bleed the master cyl. before installing it? then when you installed the new master, did you bleed all 4 points? If yes, then check all for points for leaking caliper/s and leaking wheel cylinder/s. If the van has ABS, check the valve body for a bleeder screw and see if air bleeds out of it. If you've checked everything twice and did everything right then your new master cyl. may be defective.

A grinding noise in the front end of my 2002 f250 super duty and its not the brakes

If it is a 2 wheel drive, it is probably your wheel bearings. If it a four wheel drive, it could be the front differential, the joints on the axle shafts, the locking hubs, or the wheel bearings. On the four wheel drive, crawl under the vehicle and grab the axle shafts and see where the excess movement is. Also try grabbing the tires and see if there is any movement. There shouldn't be any movement while the wheels are on the ground.
