I am leaking gear oil from the front of my differential and I assume its my pinion seal. How much do you guys think repair cost will be? I am not going to attempt this one on my own since I don't have access to a lift and don't feel like trying to do it with the car on jack stands.

I probably won't have the repair done until next month though since I am kind of tight on dough at the moment. I feel like I have lost enough fluid though that I need to top it off / change it out.

Can I get by with just adding more fluid, or do I need to drain and replace the fluid all together? Do I need a gasket for the diff cover or just use RTV sealant?

 

on a lift with air tools it can be done in an hour OR LESS !!!

 

We've got the air tools, just no lift...

 

man its prob worth it to do it yourself........then again parts & labor at a shop cant be much more than 100 bucks.......maybe 125

 

Do it yourself and it will cost you 20 bucks. Diff fluid and a pinion seal(go to checkers and get an SFK seal). Its the best seal out there dont go to auto zone and ge tthe timken seal it sucks ***.

Jack the car up level it out pop the diff cover off let the oil drain. Take the driveshaft off then use a puller to get the rear seal off. Reseal it with RTV and hammer that SOB in there and you're good to go.

 

Is the "puller" a specific tool for the the pinion seal and can you rent it from a parts store?

 

Yes, but you don't need a puller. Ford and other auto manufacturers want you to use "special" tools so you have more **** to buy, but you can usually get by without.

A hammer and flat head screw driver will get the seal out just as well as a "puller".

 

I would just do it yourself on jackstands.

 

yea ive done it on jackstands and i used the motorcraft sealer from ford and it worked awesome. On the bottle itself it said for use on diesel trucks, so im guessing if its strong enough for a HD truck then im good

 

if i had no problem doing gears on jackstands, you wont have problems doing a seal on jack stands
