fluid in rear end?

hey guys i was wondering is there something in the rear end that i should check and see if its full or if i need to put something in there like gear oil or something its on a 77 mav i6

 

You need to put in gear oil. There is a plug on the hub where you check and put gear oil.

 

Gear oil....80/90(85/90).....the check/fill plug is on the differential case....usually a 3/8" square (I use a 3/8 ratchet),oil level should be approx.1/4" below the fill plug......Hotrod-Daddy

 

And if you end up busting the 3rd member loose to drain that nasty old stuff out, be sure to drill and tap a 3/8" pipe thread plug in the bottom for later draining. I never figured out why Ford did not put in drain plugs, just a fill plug. It's a bit@# to change the fluid without a drain.

 

I agree w/ Scooper also

 

what is a 3rd member

 

3rd member... AKA pumpkin, aka Chunk, etc its the part that bolts to to the front of the rearend housing. It holds your ring gear, pinion, etc, your driveshaft is bolted to this via a ujoint.

 

I guess Ford figures the only reason you would drain the fluid if is there was a problem? Wonder what the original manual said about changing rear end oil ...

 

It's just the same-old B.S. that car makers do. The objective is to get the car out the door and make a dollar. Repair and maintainence is your problem. Take heater cores for example; everyone KNOWS that they wear out and either stop working or spring a leak. But is there an access panel for easy removal & replacment? Hell no. I have yet to see a car that has a simple access for the heater core. Sure, non-A/C Mavericks are not very difficult, but on A/C models, it's a nightmare, and that goes for GM and Chrysler vehicles too. Yep, they can put a shuttle in outter space, or a man on the moon, but can't build a car with a simple heater core access, or in this case, a simple drain plug on a differential...

 

I know that 1968 Galaxies and 1976 LTD wagons have an access door for the heater core. Very, very easy to change one. Don't even have to drain the coolant.

 

Subject line: "Fluid in rear end?"


Stay away from Taco Bell.

(sorry, back on topic please. I couldnt' resist)

 

I had no idea. ALL cars should have that, regardless of make or model. And they should also have an adequate drain system so that if it leaks, it does not spill coolant on the carpet and destroy it...
