ok so today was finally decided to take a look at what was makin the funny noise on my truck. i thought it was the U joint going bad. well i got under there and before i took a look at the joints i fiugrd ehh ill take a look at the diff to make sure its still full cause i filled it like a month a go. well sure enough i crack it open and its pretty low . no biggy though but then i look over and my tires and drums are covered in gear oil!!!! . SO GRREAAAAT. now i need help beause ive been calling parts stores to get new seals and i dont know what rear i have cause i have an oddball truck . its a 1991 dodge d350 but its a single rear axle and its got the 89 style motor in it with the over the top of the engine style intake manifold. does anyone have any idea what rear i might have? i think its a dana 70 but im not sure HELLLPPPPPPP!!!!

 

Early 91s were Nonintercooled-same as 89-90. Same engine I have. I believe our trucks our Dana 70 or 71. I dont think the seals are different from other single wheel though. I just took my seals with me and matched it up to what the parts guy brought me until I got the right one.

 

If the truck has alot of miles on it chances are good you have a groove worn in the mating surface for the seal like mine had. Do yourself a favor and check the surfaces real well. If there's any question get the speedy sleeves before you put it back together and realise the seals didn't stop it. Hindsight is 20/20.

 

They will probably try to give you seals for a D60. If the seal isn't as big around as the oil filter for the truck, it's the wrong one.

BC847 did a couple nice articles in the sticky you ought to look at. One's about cleaning out the axle vent, and another is about dealing with a grooved spindle without using a speedi-sleeve.

 

i just posted the timken part # you need in the thread about rear discs for under $260
$ 7.99 -Hub Seal – Autozone- 417158
that should be the one

 

i looked up the autozone part and it was 5.99. i went out yesterday and bought them before i looked it up and i paid 13.99 a piece because my trucks GVRW was under 9000. its 8700. does it matter if i but these in? are they the right ones? they are about 3 inches around.

 

Just make sure they match up to yours. If youre close to autozone, itd be worth the drive for $12 vs. $26.

 

i got my seals in and everythings greattttt!!!
