I just got my 3.42 locker and 28 spline axles put in today. all i have to say is goodbye 2 series open garbage and hello TRACTION!!! My car is a maniac with acceleration now and it got rid of my bogging, and it just handles oh so nice around turns. It gets right out of holes, and it leaves two nice black marks. It also hooks right up Straight and Smooth when I punch it. I never knew what I was missing out on.


Now I get to No more one line black marks. Eww. YEAH A+ FOR LOCKERS!!

 

Way to go, Joyce! One-leggers are a thing of the past.

Now when you burn 'em you're going to know the meaning of fun. and oversteer, gobs and gobs of oversteer.


Time to go do some empty parking lot donut sessions to practice losing traction and recovering it with your newfound grip.

 

Thanks man!!! i was really getting sick of getting stuck in holes and having garbage traction. My car would lean over a hole sometimes and since only one wheel got power my car would just rock and go nowhere....embarrassing. Well I do have a development circle about 500ft from my house....soooo, maybe I should test it out. I have never done a full donut with my car, just semi donuts because it just seemed wrong doing it without posi or a locker. So I guess I am in for some fun? Hmmm well see if my profile pic changes soon Thanks again!!

 

What kind of locker did you buy?? How is it, like in terms of clicking and other noises. Do you have it randomy and dangerously lock or unlock while just cruising in the corners?

 

I bought A EATON locker from the link below. I have to say this guy is a great seller. He had everything wrapped in newspaper and bags 4x over. It was crazy. I began to think where the heck are the parts. But, surprisingly there is no noise from the locker going around turns or going around turns. I have royal purple in the rear to so I don't know maybe that makes it more quiet. I love it. I have to say it was a safety hazard for me with my original diff because I drive it everyday in the winter and the open diff was killing me. I figured mise well get some better gears while I'm at it. I just need to get a new speedo gear. I was really surprised in the difference. This all went into my 7.625 10 bolt. I know people say I wouldn't invest a dime into it, or you should upgrade to a 12 bolt or 9 inch. I only have a slightly modified 305, and with a stud girdle soon to come, I don't think this rear is going anywhere. This to me is a must do upgrade from an open diff. I know the gears unlock the wheel on the outside because there is no wheel hop and it just hugs corners.

NOW I WANT ONE!!

 

Congrats on your purchase! I've gotta 3:42 in my 91' 1LE 5 speed. I'm trying to get new EV-104 28 splines for it as the originals are starting to Pit at the outer bearings. (I had a seal blow about 40km from my place and I had to drive it home slow as there were no tow trucks available and I couldn't leave it on the hwy or it would have been vandalized.) I have all the new inner bearings pinion bearing and crush sleave for the diff. Superior axles don't seem like they really care about selling parts. The local shop who is a distributor for them have to phone them everyday to see the status of the order and they just get some roundmouth on the phone saying they haven't been sent yet. This has been going on for a month now. How much was the Eaton with the shafts? Does the guy you got yours from have a phone # available? I'm tired of F'n around with these people.

By the way be careful in the winter with your new posi!!!! Put winter tires on it at least. It will slide your rear all over the place. If you hit any ice on the hwy with the least bit of throttle you'll spin it out before you realize it. I don't drive mine in the winter, it is virtualy uncontrollable in winter.

sorry looks like he only had one.

 

I'd give my left nut to get rid of my locker. I have the powertrax no-slip. Instead of writing out my distain for it again just look for my posts about it.

 

ok what do u mean it handles better in turns?

 

Congrats on the new rear. But to put things straight, you don't have a locker. You have a limited slip. A locker is something that positively engages with power given to both wheels equally. A limited slip will allow one wheel to spin at a different speed than the other (better in rain and snow). A locker is great for drag racing, but horrible in a day to day car. I drive my car, and would like to take it out to the track (road course, not drag). For me, limited slip works best.

 

prolly a dum question but will that fit in any f body rear?

 

Are you sure it's not a locker? When I looked up the casting numbers they came up as a locker, and limited slip engages both wheels after a couple seconds when you burnout. My wheels both spin at the same rate when I burn out, no lag at all. The seller also called it a locker too. I know every locker carrier clicks when it goes around turns. But it doesn't have any click so you could be right.

Alaska Hwy 1Le just ask him is he has anymore. Because when I got mine he said he had 3.73's as well and other gears. I wanted the 3.42's for highway. I am sure he still has more if you want one. Yeah I am going to be buying my winter tires soon because they go on sale in the summer. Thanks for the tip.

LouStugots it's not a dumb question. I am pretty sure it depends on if your rear is a 9 bolt, or 10 bolt if it's stock. I think most 1982-92 thirdgens are 7.625" rear ends. Don't take me up on that, ask the board or somebody here.

 

Looks like a locker in the picture on the link provided..

 

Looks like a Eaton Gov-Lok limited slip out of GM's small trucks. Not a performance limited slip or a true locker, and I think you bought something without really understanding what it was. Also overpaid. You want more info about do a seach Gov-Lok. Picture of LS

 

Pretty much! The ten bolts for sure

 

Technically it's a limited slip positrac. It allows the 2 wheels to spin at different rates when turning but will still apply power to both wheels. Yours will click and snap when doing tighter turns too IF you run synthetic gear oil in it or if you don't have the proper limited slip additive chemical. The additive is a friction modifier to allow the clutchpack in the diff to slide or rub smoothly otherwize they grab eachother until the torque difference is to much then they snap loose. A real genuine locker is in fact like having one solid axle between the two wheels (Like a chain driven racing quad). Lockers can also be engaged and disengaged manually from the cab.

 

damnn i want one i hate the one wheel peels soo gay

 

Pretty sure a locker will still allow the rear wheels to turn at different speeds in turns. The locker doesn't use clutches to achieve the limited slip like a Post does. It ratchets when turning, so you should hear a clicking noise.

Now there is another rear-end type called a spool , will not allow tires to turn independently under any circumstance, and is defiantly meant for the drag strip or for off-roading 4 wheel drives.

Check out this link:

It describes several different lockers.

 

I wouldn't say that you overpaid. With the gears and axles included, it is not a bad price (if everything was in good condition). The seller has lots of facts wrong in the auction though. 7.5 housings never came with 28 spline axles in the F-body. Also, the GM LSDs are not that good in the 7.5/7.625 axles. Hell, if someone wants one I have a burned out stock unit sitting in my old housing. You can not buy replacement clutches for them, so once they stop working correctly they become very heavy paper weights. The only LSDs that were good from the factory came in 4th gen cars that had the SLP upgraded diff (98+ if I remember correctly). Though the standard 98+ (once again, if my memory serves me correctly) LSD is better than any of the previous versions (due to the design it did not use clutches). 88/89 were the years they started introducing 28 spline axles, and is the year you have a chance of getting either. Otherwise 28 spline was the norm, not the exception.

 

Limited slip additive isnt needed with this diff due to the fact that it isnt a clutch type posi at all, it's, as was mentioned above, a gov-lock.
Edit: Unless you were refering to the picture of the posi unit posted by djp..

 

Their are two basic types of lockers.

One you have to lock in. Should act like a open diff until locked. They are cable or air operated.

The other is an automatic locker. They will allow one tire to lose power during turning. Otherwise they will act like a true locker or spool. You just don't have to lock it in.
