1994 K1500 6.5TD "S" auto: 10 bolt or 14 bolt rear diff?

[chi2]

I am trying to order some gaskets from my local auto parts retailer, but my truck is inaccessible until this weekend (at a friends- he is out of town).

To order gaskets for my front and rear differential, I need to know if the 94 K1500 "S" 6.5TD, auto trans, came with a 10 bolt or 14 bolt differential cover.

If anyone can send me that info, it would be great to order the gaskets today.

Thanks.

It would depend on which gears the truck was manufactured with. i.e. 4:10, 3:73, 3:42 etc. etc.

I just looked up my VIN sheet:

F44 -- CHASSIS, HEAVY DUTY
GT4 -- AXLE REAR, 3.73 RATIO
G80 -- AXLE REAR, LIMITED SLIP (POSITRACTION)

It looks like my question should have been: Does the 3.73 gear ratio differential have 10 bolts or 14?

Thanks.

My truck is 2WD but has the same rear end as you discribed 3:73 limited slip posy. and it has 14 bolts.

my 98 K1500 3:73s has 14 bolt semi floater rear diff, IIRC www.lmctruck.com has a pic of diffs

4X4 1500 should have the 14 bolt 9.5" semi-floater. A 2WD 1500 with low gears could have came with a 10 bolt, or a 14 bolt semi-floater.

IMO it is better when in doubt to buy both and return the extra later. Your time is worth more than the couple of bucks for the gaskets.

you have a 14 bolt rear... the semi floating 9.5"er

Go down there and count the number of bolt. Easy enough.

 

[North Maine]

um, he said he can't get to it

 

[chi2]

Yeah- I can't get under the truck until Saturday, which is the day I want to do all the work (and the parts place needs at least one day in advance to order it).

Thanks for everyone's help. Based on your input, I expect that I do have the 14 bolt rear diff cover, but I also followed Pillow's advice and ordered both just in case. :smilewinkgrin:

Thanks!
