Do i have to remove the differential housing cover to remove C - clips or can i just unbolt the hubs and remove both lock nuts on the hub because I want to check my rear brakes on a 65 chevy 3/4 ton...


Hi! sensenicht
Are there bolts on the outer hubs. If so removing the axel hub bolts will allow you to pull the axles. You should be able to remove the lock nut, lock washer and adjusting nut (second nut) to remove rear brake hubs and drums. The C-Clips are only used on the half ton and lighter cars. This is called floating axels.
Its important to replace the hub seals on the inside of the drums. A small amount of axel greese will make your brakes not work properly.

What do i need to take apart to remove the drivers side front drive axel to replace the universal joint at the hub? could the axel slide threw the hole for the axel berring assembly or do you need to take...


Have not done this on your truck but book says just the upper ball joint needs separated. See procedure below from autozone.com. Please let me know if you have questions.
  1. Remove or disconnect the following:

    Front wheels (left side should be sufficient in your case) Front hub cotter pin, retainer and nut (axle nut)
  2. Using a floor hydraulic jack, support the lower suspension arm.

    Upper ball joint cotter pin and castle nut Knuckle from the front suspension upper arm
  3. Lower the lower suspension arm and steering knuckle slightly to facilitate easier halfshaft removal.
  4. Remove the 2 disc caliper mounting bolts, then lift the front disc caliper off of the front disc brake caliper anchor plate and position aside. Do not allow the caliper to hang by the brake hose; suspend it from the vehicle's frame with strong cord or wire.
  5. Remove the 6 front halfshaft-to-differential bolts.
    WARNING Use care to avoid damaging the hub seal when removing the front halfshaft.

Fig. Halfshaft-to-differential mounting bolts (3 of the 6 bolts shown)-2001-03 F-150 and 2004 F-150 Heritage Edition


7. Remove the inboard end of the halfshaft from the differential case or extension axle case. Separate the front halfshaft and joints from the hub, then remove the halfshaft and joints from the vehicle.



To install:

  1. Slide the halfshaft outboard end into the hub, making sure that the splines engage.
  2. Situate the inboard end of the halfshaft against the front differential flange and install the 6 halfshaft-to-differential bolts. Tighten the halfshaft bolts to 60 ft. lbs. (82 Nm).
  3. Install the front disc brake caliper onto the rotor and anchor plate, then install and tighten the 2 caliper mounting bolts to 21-26 ft. lbs. (28-36 Nm).
  4. Lift the lower suspension arm and steering knuckle up until the upper ball joint stud is inserted into the steering knuckle. Install the upper ball joint castle nut and tighten to 57-76 ft. lbs. (77-104 Nm). Install a new cotter pin.
  5. Install the hub nut onto the halfshaft and tighten the hub nut to 221 ft. lbs. (300 Nm).
  6. Install the hub nut retainer and a new cotter pin.
  7. Install the front wheels and tighten the lug nuts in a star-shaped sequence to 83-112 ft. lbs. (113-153 Nm).
  8. Lower the vehicle to the ground.

How do I replace a lower balljoint on a 97 GMC Jimmy 4WD?


Unless you have some kind of a press to press the old one out and the new one in, better take and have it done.
Need to take the tire off
brake calipar and rotor and bracket off
take the 4wd locking hub assembly out
there is nuts and locking rings in there
pull the axel. Pull cotter pin from nut on ball joint stud, take off nut, separate ball joint from steering knuckle with seperator tool, then you need to press out the joint, sometimes the top joint has to be taken off too. It's a job, and you need the right tools.If you don't get the 4wd assembly back the same way, you have 4wd problems.

How do you replace a front axel shaft


Old technology dana axle, i believe. If so youll need the brakes off and rotor and the whole wheel bearing hub assembly(i believe bolt in with 4 bolts) this leaves pretty big open hole to draw out axle through. No c-clips or anything holding the axle in. just pull it out. Hope I helped. Thanks

There should be a big nut in the center of the wheel hub. You will have to remove atleast one of the ball joints if it's IFS.

I need to remove the brake drum on a 1976 gmc sierra 25


Soak it with generous amounts penetrating oil around the lugs and let it sit for a while and soak it again and hit it with a bigger hammer. There arent any hidden bolts they are just stubborn sometimes (most of the time).
