Limited Slip questions

Hey,

I was thinking bout replacing the rear end in my 99, 2WD 4.3 blazer. I'm sick of always getting stuck in the Snow/ Ice. What kinda parts should I get to get the most bang for my buck. I was looking around here and the general consenseous is that posi isn't the way to go for everyday use. I'm just starting out with improvements for my ride. The most I got is a K&N air filter in the stock air box. So yeah Help is greatly needed

You can replace the rear end with a posi and there is a thread recently telling you how to do it.

What about putting a locker in there?? Would that be something that I could do??? Pretty much, what's the cheapest I can do to get posi going?? Without pulling a "Joe Bob grab the welder"?

LOL, I like that.. Do you personally have something against a joe bob?

No, not really. If that's the way someone wants do things, all the power to'em. Although, these are the same people that think Duct tape is the next best thing to moonshine and had friends who's last words were " Hey Ya'll check this Out!!!!"

Hey, I resemble that remark! :ylsuper:

Sorry to hear that,

How Long have you had that problem??

J/K, but seriously I got my truck here needing some posi in the worst way. Any ideas anyone??? Oh, wait a sec, and Joe Bob wants his tooth back. I don't know, something bout trying to eat a caramel apple for the past couple days.
I can't understand him, he sounds like Sloth chocking on a Baby Ruth. So yeah, now both of us need some help.

Any reason why you are posting in the Blazer section with a BMW concern?

Hey Guys,

I talked to a couple of people and the only way I can get a locking diff on what I got right now is to throw a clutch style locker in there and from what I got on the net those suck. I can't throw a mechanical locker in there cause I got a 7 5/8 rear and they "the guys at the off road shop" said it's not do able.

Now the idea going right now is to swap the rear end with a ZR2 rear 8 1/2 w/ the 3:73 rear and POOF. Question is has anyone done this or is it at all possible without having to transform my truck into friggin Optimus Prime. I know that the ZR2 rear is wider which would look cool with the those fender flares. It's a 2WD so what effect will this have all around???

If you're really don't want to get stuck in snow then it makes more sense to sell the 2wd and buy a 4wd.

Oh Thanks,

Now why didn't I think of that????


You wanna know why I don't? Cause I don't have the 15G's to spend on another ride none the less a 4x4. Thanks Genius, You know what would really make sense?? You actually knowing the answer to my question and not telling me Shit that has no relevance. I think you got your head stuck in the snow, there snowflake.

kid, quit trippen, he gave you the right answer, dont be a dick about it, your two choices are, 1 swap the rear end out with one that is already a posi, or buy a 4x4, just because the right answer isnt what you alwase want to hear, doesnt make it wrong

Hey I ain't trying to be a dick but, Think about it, why would I be asking questions about swaping my rear end if I had the means to get a 4WD truck???

I didn't join this forum to get options. I joined to get answers to my question. I never asked "Hey guys you think I should swap my rear end out or get a 4X4?? Straight up

If you wanna play Tic for Tac Fine we can go and do that on IM, but here.. I much rather keep it Q&A and relative to the question. Keep the 2 cents in your pocket and I'll more than gladly do the same.

Limited slip should help you out a lot.

Thank You,

I think I'm gonna go with the ZR2 rear with the 3:73 diff. There was issues as to where the springs would mount considering the 2in difference on either end. I got those guys cutting'em and welding them where they need to go so from there it SHOULD be as easy as legos. It looks like it's gonna run me $800 just for the rear end, not to include putting it in. Hope it's worth it

find out what gu number you need then check local j yards for the rear end, pulling it yourselfe will usually save big $$, and i didnt mean to sound like an ass earlyer, but here, you will get the answers that are the most simple and cheepest, ie sell your truck and get a 4x4, or the ones that you wanted to hear, even though no one else can figgure out why you dont do it the other way, a 4x4 would defenetly be easyest, but to do the reare end, if you get the full rear end from your compatible year truck, you should be able to unbolt then bolt back up

You do realize that the zr2 rear is about 3-1/2 wider than the normal 4x4 rear don't you? You're rear wheels are gonna stick out a lot.

I know that it's gonna stick out farther but, What the Hell. I could always put on extended fender flares and call it good.

Gonna look silly with the front tucked. Why not just get a regular 8.5 4x4 g80 rear instead?

sounds like the kids trippen.

If you look at it, the front wheels stick out about an inch and a half wider on each side than the rears.

I had 1.25" spacers (total of 2.5" wider) on my rear wheels and they were still tucked in the fenders. The width w/spacers actually looked identical to the width of the front wheels. Another half inch on each side (3.5") would look fine.
