Posi Rear End

[Brantly]

Hey guys, im about to be putting a yukon posi traction carrier and a 4.88 ring and pinion and all new bearings plus seals in my rear end tomorrow. I think i understand the use of the shims in order to get a good connection with the gears and the backlash correct, do you guys have any dos and don'ts for me? Or any tips/things i should lookout for? Its a 8.5" 10 bolt rear end.

Instead of using a crush sleeve get this kit and a couple extra bearings, open them up a little so they slide on/off easily while you're setting preload. Much easier this way.

Get an inch/LB beam wrench for this.

You must be registered for see images attach

And a dial indicator for backlash.

Here's a guide on how to, if you don't already have one.

Thanks for the reply! This is the kit i bought https://www.summitracing.com/parts/yga-10400
i believe it comes with all the bearings ill need and it says with shims too but could it be crush sleeves? or would it specifically say if it did. id much rather have the shims

Personally I would stay away from the Yukon carrier and get an Eaton instead. More money, but we've had members here who have had issues with the Yukons.

According to your link it shows it includes the crush sleeve and has the bearings but does not include the sacrificial bearings I linked so you can set your preload easier. I still suggest you get what I linked too. If you don't get it right, it'll whine and howl until it breaks.

Eaton Truetrac. Trust me. I put one in my 10 bolt Suburban. Great posi.

thanks everyoje for the advice, decided to scrap the yukon posi and get a tru track instead, keep hearing too many bad things about the yukons!

I've been eyeballing one of these:

https://www.4wheelparts.com/p/power...ro-traction-system-gt201030/_/R-BHKT-GT201030

I'd never heard of them. Looks good but I'd like to find out what the torque bias ratio is with the GT201030.
