My winter project...

Well for as much winter that we actually get here. Decided to redo my rear suspension with UMI non adjustable upper/lower rear tubular control arms, install a Nitro Gear and Axle Lunch Box Locker in my BOP type O peg leg rear, and replaced the shocks.

The locker was easier than I thought it would be once you get in there. Basically you pop off the rear cover, back the axles out about an inch or so on each side, pull the cross pin, remove the spider gears, transfer the thrust washers to both sides of the locker, assemble it in place, install the springs, replace with the new cross shaft, put the cover back on, and your done. With the whole rear off the car most of the work was pretty easy just sitting on my roll around stool.

Although I got it all finished, today it was raining so test drive will be tomorrow.

Re: My winter project...

Took it for a short ride, a couple of hole shots, and a bunch of left and right turns. It drove really well with no strange noises or leaks... Life is good! The locker does click when you turn as each axle breaks loose within the locker, it kind of sounds like when as a kid you put a playing card against the spokes of a bicycle going slow. The new control arms are a great improvement over the worn out bushings in the old stock arms and the addition of the sway bar is remarkable. The KYB shocks stiffened the ride over the 11 year old leaky Monroe's. It was a plus to pull the differential out completely to do the locker and change the upper bushings. The arms and sway bar were a snap. No special tools required.
To recap:
UMI ABR401B kit, upper and lower control arms with poly bushings front and back. $315.00
UMI 4034B sway bar. $144.00
Nitro Gear and Axle Lunch Box Locker. $375.00
2 qts of Valvoline 85w140 gear oil. $13.00
2 KYB 5507 gas adjust rear shocks. $62.00
Grand total = $909.00

Re: My winter project...

Looks nice Eric. What paint did you use on that rear housing? Looks like you did a nice clean install with those rear brake lines. I like that brake line mouning bracket too. I'm not sure that I've ever seen one like that before. But that might be due to me being so used to looking at aftermarket rears, in modified A-body cars. So I must also ask you if that's an after market bracket or a factory stock replacement one? I'm guessing that it's aftermarket. I've only seen ones that mount directly onto one of the pumpkin cover bolts.

Re: My winter project...

I was excited to here you had a Olds and you used a Nitro Gear locker in it. Searched the web site....They don't offer that for the 8.2 BOP case. Damn.

Then I saw your running a 12 bolt rear end...

I used hi temp Dupli-Color DE1613, gloss black ceramic engine enamel. The brake lines were just cleaned and painted silver. The rear is the stock type O that came in my 67 Cutlass with the stock brake line mounting bracket that bolts to the housing.

As I said above this is my stock rear is a 3:08 type O, 8.5 inch 10 bolt ring gear, and 28 spline bolt in axles. I believe the person that set me up with my locker possibly can help you with your 8.2, no one listed one for my 8.5 either. Send me a pm and I can get you his info. He's very knowledgeable about bop rear ends.

Mine chatters (clicks) also in turns. I'm under the assumption that is normal due to the different tire speeds when turning and the locker teeth ratcheting around.
I like the fact that I can get more of the HP that my 468 puts out through a T400 with a 2800 stall converter on to the ground. And yes the perk of 2 solid stripes is fulfilling.

I have a Detroit Locker, ( I haven't used it yet) but I'm told that this is normal for Locker rears, (like you've said). In fact, I was also told that at least with some Lockers, once in a great while you can also get a loud bang too. But like with a lot of things in this game, that's the trade-off which comes with greater durability.

Please let me know if you notice the car pull to one side or the other during gear shifts. I'm told that this also can occur with Locker rears. It's for that reason that I might end up going with a spool for the drag strip. I wouldn't want the car pulling to one side while the front tires are airborne. That's a recipe for a barrell roll. IDK if the Locker will hold up to transbrake launches in my car anyway. I was also told that once you get into the 1.3 second 60 foot time neighborhood with heavy weight transbrake cars, that's when the Lockers tend to go bye-bye. But excuse my digression. I'm sure that none of this applies to your car. Just kinda thinking out loud here. Anyway, it looks like you're doing a very nice job with your build.

Re: My winter project...

My build is now officially and firmly in the driver classification of maintenance mode (basically fix what breaks). Everything on the car has pretty much been repaired, replaced, and/or inspected front to back, top to bottom since 2009. The car has come a long way. The intent of this car was to build a decent car for cheap and in this day and age that has become an impossible task. I've got about $18k in it including the car with me doing 90% of the work. It was never intended to go to the track, but someday I'd like to see what it can do.
