The noise is not coming from the pinion seal, but the pinion bearings are bad and this is why the pinion seal is leaking. You will need to have the rear end bearings and seals replaced (https://www.yourmechanic.com/services/pinion-seal-replacement). If you'd like...

The flange is integral with a splined yoke. The yoke segment (of the flange/yoke) has a precision, machined, highly polished surface which mates with the rubber seal (https://www.yourmechanic.com/services/pinion-seal-replacement). Since the rubber seal is spring loaded and is under tension against...

Motor vehicle safety inspections in almost all U.S. jurisdictions do not cover maintenance and ordinary wear and tear, including de minimus "leaks", unless the "defect" found creates an immediate, obvious, and direct impact on the safety of the vehicle or...

I believe that the issue you are having is due to your rack and pinion. If you are hearing a squeaking sound from the rack and pinion, there is likely a restriction in your rack and pinion most likely due...

Basically, any bolted on or "jointed" moving part or bushing could account for noise in the front end. Not included in your list are rack and pinion mounts/bushings, strut bearings, tie rod ends, even brake parts (caliper torque plate), loose...

If you have not had any maintenance done then have a complete computer scan test (https://www.yourmechanic.com/services/check-engine-light-is-on-inspection) done to see if any codes are present. Perform any maintenance needed like air filters (https://www.yourmechanic.com/services/air-filter-replacement), fuel filters (https://www.yourmechanic.com/services/fuel-filter-replacement), and oil changes (https://www.yourmechanic.com/services/oil-fluid-leak-inspection). You...

It is highly unlikely that these two issues are related. The issue you are likely having is that the mode door actuator has failed. The mode door actuator controls the mode door which will move in different directions to block...

Here's the thing--power steering fluid is what gives you power. The pump pumps it, sends the power to the rack, which makes it easy to turn. If it all leaked out and you drive it, it will burn the power...

High pitch brake noises are usually caused by the wear indicator on the brake pads. This is a thin piece of metal that makes contact with the rotor with the brake pad lining gets to about 20%. The noise is...

Hi. The pinion seal leakage is a pretty common problem on older vehicles with differentials. It is generally a pretty inexpensive repair. Lack of fluid can be catastrophic to the differential so it is recommended that the leak is fixed...

The steering gear leaking is best serviced by replacing it with a new or remanufactured unit. The hoses should be checked also. I recommend you have a mechanic like one from YourMechanic inspect your vehicle for power steering leaks (https://www.yourmechanic.com/services/power-steering-fluid-is-leaking-inspection)....

There are very few advantages to the pitman arm style over the rack and pinion style. The rack and pinion style has less moving parts and, therefore, less causes of failure. The rack and pinion system is also lighter in...

I would replace the whole rack and pinion. You could try a rebuild kit if you want but as a technician I would suggest getting a new one. If you would like to verify the cause of the leak before...

Hello there, thanks for your question. The pinion flange is a part of the rear differential housing that the driveshaft bolts to. The other end is attached to the pinion gear inside of the differential. The pinion seal is what...

Hey there. I would suggest having the inner and outer tie rods (https://www.yourmechanic.com/services/tie-rod-end-replacement) checked for looseness and replaced if any play is found. When checking the rack and pinion mounts and bushings there should also be no looseness. The steering's...

You have two pinion shaft bearings. The one that can be replaced by removing the driveshaft and flange on the rear end. You remove the seal and the bearing can be removed. The bearing race cannot be replaced this way...

Yes, why not get a used unit? Unfortunately, replacing those pinion things is a very complex and involved job. You need years of experience for a job like this. Now, sometimes I would take the differential off of a vehicle,...

The pinion bearing is a common issue with Ford rear ends. Most of the time, this failure is due to a differential leak that was not addressed and the bearing run dry. I recommend having a trained technician, such as...

CV axles leak from the a dust boot. Inside the dust boot is a special high temperature grease that provides lubrication to the joint. If the grease leaks, the joint will be damaged from the lack of lubrication and extreme...
