front 10 bolt differential bearing cap torque?

[jeff in co]

I just changed the front axle seals of my 10 bolt axle out of a 3/4 ton suburban and don't know the torque setting for the differential bearing caps (4 bolts). I've looked in my Hayes manual and just can't seem to find it.

I basically pulled the whole carrier out, replaced the axle seals and have now put it back together.....just missing the torque setting.

Thanks!

I want to say its right around 70-80ftlbs

I found a thread that said 85 so still up in the air just a bit.....I'll keep researching but it looks like it's in this 70-85 range.

 

[jeff in co]

found another site that said 60 was the correct one.....so I guess at minimum, I'll do 60 unless I find something different.

It's 60. That's plenty for those little bolts.

I wouldnt consider a 7/16ths bolt to be very small...

If we are talking the 4 bolts connecting the Bearing Cap to the Steering Knuckle... The 87 Service Manual says:

Tighten 4 Bolts alternately and evenly to 108 N-m (80 Ft Lbs)

I agree. I was kinda comparing it to a 60 or 14b in my head.

He is talking about the main cap bolts for the diff carrier

Cool! I went with 60 and I actually just finished swapping in the new axle. Everything went smooth with the exception of the tie-rod end got stripped. It looks like it's sealed so I may have to get a whole new rod.....dang!

However, long story short. I swapped in a 14 bolt SF axle from a 3/4 ton suburban and ended up using a small spacer and the smaller, 6 lug brakes and axle shaft. Worked out great and now I have 4.10 gears too!

^^^^^^ Yep.

Oh, one last thing. Someone mentioned locktite on those carrier bolts. Is that necessary? Seems like it wouldn't grab too well anyways because of the gear oil in there.

I bet it worked OK... Was wondering when I'd hear from ya.

Nope. Only on the bolt that holds the pin in the carrier.

Yea, a little tired over the past few weeks! Wife and kids went to Florida so I had time for the rear. Had the e-locker installed, used the spacers and swapped it in. I've been driving it for a week and it's great!

Decided to do the front axle today and got it in with the exception to the tie rod ends. But, I dug in my receipts and found out I bought it from Autozone and it has a lifetime warranty! Sweet!

I'll post up some pics later but they look just like yours. Nice and clean!

Thanks 1Beat....appreciate the help!

I was kinda watching your progress. I had no email or PMs so I guessed everything went as I said it would. Glad it went smooth!

 

[jeff in co]

Yea, I was going to shoot you an email but my phone didn't find it.....

Anyways, appreciate all the help! I stuck with the larger studs in the back and the stock ones in front. May change later.

 

[jeff in co]

And also got the roll bar in a few days ago too.....

Grasshopper follows plan well! haha!

Love the clean undercarriage. Looks like an awesome LD rig.
