How do you change a pinion seal on a Ford 9 inch?

How to Change a Pinion Seal in a Ford 9-inch Rear End

  1. Park the vehicle on level ground.
  2. Mark the U-joint cap and the pinion yoke with white-out where the cap is seated.
  3. Place an inch-pound needle-type torque wrench and socket on the pinion nut.
  4. Mark the pinion yoke and the shaft with white-out so you can realign the parts when you put it back together.

What causes a pinion bearing to go bad?

Sometimes the carrier bearing fails due to extreme working conditions, poor handling or improper installation, and sometimes due to lack of lubrication or some other related problems.

What does a bad carrier bearing feel like?

Unusual noises are some of the first symptoms produced by a bad or failing center support bearing. An excessively worn or faulty center support bearing will howl or squeal when the vehicle accelerates from a stop. The howling or squealing may quiet down as the vehicle picks up speed.

How do you diagnose a bad rear differential?

5 Signs of a Failing Differential

  1. Tire Damages. If you notice strange damages on the sidewall and outer tread of your vehicle’s tires, it may be caused by failing differential components.
  2. Hard to Handle.
  3. Vibrations.
  4. Gears Grinding.
  5. Whining Sounds.

How long will a rear differential last?

A rear differential service consists of removing the rear differential cover, cleaning any old fluid from inside the differential case, resealing the cover, and adding clean fluid. After a rear differential fluid change, most vehicles will go 20,000 to 40,000 miles before it’s due again.

How hard is it to rebuild a rear differential?

A complete rear differential replacement includes replacing the housing, gears, bearings, and seals. The average time it takes a certified mechanic to perform a differential rebuild at a shop is usually three to five hours. A rebuild on a commercial vehicle by someone without prior experience could take much longer.

Is rebuilding a differential easy?

Services: Differential Rebuilding. Some differential issues can be fixed easily and do not require a rebuild. An experienced, knowledgeable mechanic can inspect your vehicle’s differential for the tell-tale signs of serious wear and tear, damage, and other general problems.

How much does it cost to rebuild a Chevy rear end?

Minimum is about $900 which includes all new carrier, pinion bearings and axle bearings and all new seals. If the Ring and Pinion gear is ruined then that would add another $500-600. Hopefully the differential housing is ok because that would involve even more $.

What tools do you need to rebuild a rear end?

Differential Repair Tools

  • Race Driver Sets.
  • Dial Indicators.
  • Dial Calipers.
  • Bearing Pullers & Adaptors.

What tools do you need to rebuild a differential?

Bearing pullers, dial indicators, brass punches, spanner wrenches…all of these specialty tools are required to swap ring and pinion gears and get them set up properly. There are also differential tools that make the job quicker and easier.

How do you use Rateion pinion depth tool?

With the tool being held by your left hand firmly against the top of the pinion head and the slotted end touching the face of the axle tube, insert the dial caliper with your right hand into the slot and position the depth rod so it touches the bottom of the carrier bearing journal.

How do you set pinion depth?

Pinion Depth – The distance from the face of the pinion gear to the centerline of the ring gear. This is adjusted by adding or subtracting shims to the inner pinion bearing.

Does crush sleeve affect pinion depth?

Re: Pinion depth/crush sleeve question Changing the pinion seal will in no way change the pinion depth. Pinion bearing preload is set by tightening the pinion nut until you crush the crush spacer enough to load the bearings.

How tight should a pinion nut be?

Be careful a quarter turn past optimum is way too tight. You only want 12-20 in. lbs of torque on the free spinning pinion. If you go too tight, the only thing to do is take it apart and crush a new sleeve.

How important is pinion depth?

Increasing pinion depth also decreases backlash and moves drive pattern slightly towards toe, and coast pattern slightly towards the heel. Decreasing pinion depth also increases backlash and moves the drive pattern slightly towards the heel, and the coast pattern slightly towards the toe.

Does pinion depth affect backlash?

Decreasing pinion depth also increases backlash and moves the drive pattern slightly towards the heel, and the coast pattern slightly towards the toe. Increasing pinion depth will also increase pinion-bearing preload unless the outer pinion shims are adjusted.
