Weight of rear diff

gomer_110 · 03-15-2016, 08:14 PM

Does anyone have a good approximation of what the rear diff weighs?

Trying to decide if I want to tackle installing my new lsd myself or just take it to a shop.

All I can say is that it is f4rking heavy .... I can lift it myself off the floor (just) but you will require a transmission jack and the car in the air to do anything with it.

Forget any idea of holding it above you head yourself.

Unless you have a hoist and transmission jack, forget it - not worth the hernia !!

Yep

that's about what mine weighed when I shipped it to it's new home.

To the OP as mentioned, they have these things called floor jacks that make it easier to manipulate.

85lbs. with rear cover bolted on & oem front mounts attached (no oil)
that is with a Quaife ATB (QDF10L) installed for an A/T ~Z~
Did not weigh it with open diff. (carrier w/spider gears & cross pin)

Thanks for the numbers.

Think I'll just take it to a shop based on the weights.

I'm 62 and I had no problem R&R this.

greasebeast · 03-24-2016, 02:25 PM

i'd take it to a shop, if you drop it out yourself and bring it in they'll only charge you $150-$250 for the install

jchammond · 03-24-2016, 08:26 PM

A shop? I am my shop; with the cost of upgrades for this thing/ would never consider letting anyone else do it.

I did mine by hand. By myself. It was terrifying lol.

JARblue · 03-27-2016, 09:35 AM

A couple years ago I bought a transmission jack on sale at Harbor Freight for barely $100. Might be a good option now and could be useful in the future

Masterbeatty · 03-27-2016, 10:50 PM

Yea i pulled it out on my chest but had to use a motorcycle jack to install it. But i also had the quaife and oil in it.

1slow370 · 03-31-2016, 02:56 AM

haha yeah i had it at 87lbs with fluid, and i won a bet against a coworker once, he didn't think it was possible to pick it up, lift over your head, position it on the car on a lift and start a front bolt by hand. I got pics somewhere.

I use my floor jack. to take the Differential off and put it back on. When removing it, I removed the bolts 1/2 way then placed the jack under her. Jacked the diff up a little and twisted the rest of the bolt out by hand. All that was left is to gently pry the rear out and she is free. I think I used a strap on her to keep her secured to the jack too.

When I put here back up, I had a 2nd hand instead of strapping her down to keep the differential steady as I slid the rear in and put te 2 front bolts in.

Yeah it's heavy but not impossible. I made a youtube video on how to remove the old junk and install some Whiteline Poly bushings in a while back.

Here is the first video. There are 9 in total. It really was not that bad of a job. It's just a little messy and took like 4 hours or so. I had to stop and record a few times. Then watch the vid to see if it was any good and record again or proceed. I had another video recorded but never uploaded it. It showed where I used a paddle bit to drill the rear bushing multiple times all the way way round. I had used a spiral type and it caught and then snapped in half on the first attempt. I then proceeded to the a 8 ton bottle jack. The jack was wedged between the bushing and the main frame.Wood was used to get the jack piston to touch the rear diff bushing where I then used it to force the middle rubber part out giving me plenty of space to fit a saw blade to cut the metal ring.
