Leak in rear axle

Hi, I have a 1986 F250 3/4 ton with a 302 engine. I'm wondering how to go
about getting access to the seal which I think is the problem. The info for
the axle on the inside door is 27 thats all it says for the axle. Theres a small
tag on the rear end and the #'s are as follows...3...V1O8B and below that is
3. 731026H28 And I was going to take off the rear end cover but I didn't see
any place to put new gear oil in. Anyway, thats what I would like to find out.
Thanks in advance, Rick

    If I could unbolt the axle I would not have to make this post. I don't have 6 or 8 bolts that stick out
    from center of wheel. How do I send you a pic of my axle?

You will need to unbolt the axle and slide it out there should be 6 or 8 bolts on the hub that sticks out of the center of wheel. take this out and there is a spanner nut inside you will need to bend back locking tab and unscreww nut and drum and hub will slide off you will see seal inside hub

    SORRY there is different axle options on these trucks

    1. Raise and support vehicle, then remove rear wheel and brake drum.
    2. Loosen rear housing cover screws and allow lubricant to drain, then remove cover.
    3. Remove differential pinion shaft lock bolt and differential pinion shaft.
    4. Move flanged end of axle shaft inward and remove C-lock from end of shaft.
    5. Remove axle shaft from housing by pulling outward.
    6. Reverse procedure to install. Apply Loctite EOAZ-19554-B to pinion shaft lock bolt threads, then torque lock bolt to 15-30 ft. lbs.

    there should be a plug on the side of differential a 3/8 ratchet and extension will fit in it i think it is on right side behind pinion

    no problem good luck. be sure to check your axle for a groove where the seal rides as this can cause a leak even with new seal

Rear axle seal leak repair

Is that not a question for a dealer or a local repair shop,
you choose to deal with?

Instead of coming here & wondering, while still using the
vehicle & possibly run the axle low on fluid & ruin that

You should have had it repaired already

You stop using any vehicle the moment you know or find any problem

1984 Chevrolet Custom Deluxe rear hub service

If you can see inside the wheel bearings then they require lubrication from the differential. If they are sealed then no. You don't say if the rear axles are 1/2 ton or 3/4 ton. No brand of seal will seal better than any other. Spray engine degreaser in the rear end and flush out with water. You may need to do that more than once.

Rear axle seal leaking how difficult would this be to fix

Not that difficult, raise and support the rear of the truck and remove the wheels. Might as well replace both sides so you know you have new seals, remove the differential cover and drain the fluid. Once differential is opened and cleaned , remove the axle "C" clip that hold the axle in place and slide the axle out. Once the axle is out remove the wheel seal and clean around the area. This would be a good time to replace the wheel bearing too since you have access to them and there not that expensive. Install the new bearing and seal, note make sure you oiled the bearing and seal before installing it back and take care when installing the axle back in and "C: clip. Use RTV silicon gasket maker to seal the differential cover and wheels back on and lower. If your lazy like i am, you can drain the differential fluid and replace it with a 50/50 mix with gear oil and Lucas engine oil additives. That may stop the leak and get you a few more miles. You gear oil is 75W-90 and the capacity is 2.6 liters and 3.6 liters if you have the 11.50 Ring gear. Good luck and hope this helps.

My 1986 toyota cressida leaks transmistion fluid out bottom of car where drive line connects to transmisson the transmission is fine how do i fix it

Based on your description I am going to assume your leak is @ the rear of the transmission. If so, the leak would most likely be from the transmission output seal. To fix, you will have to remove the drive-shaft by unbolting it from the rear axle and sliding it rearward out of the transmission. Once the shaft is out of the way, you will need to remove the seal by inserting a pry bar or large screwdriver between the transmission output shaft and the seal lip and pop it out. Sometimes you may have to partially collapse the steel shell inward towards the center with a small chisel and hammer to releive the press fit. Drive the new seal into the bore and reinstall the driveshaft. Check fluid, road test and check for leaks after the road test.

Rear axle bearings

There are 4 bolts for each rear axle. They are located behind the rear brake drums. Remove e-brake cable from rear drum and take off brake line.(carefully). I recomend draining and changing your rear differential fluid too, because if the fluid by run out of axle housing. also you should replace the seals for the axles of if you are changing the bearings. When you are done don't forget to bleed your brakes, and hooking up e-brake cable. I hope this answers your question.
