Here is a shot of the Camaro getting worked (800whp). I gotta say whatever they make their transmissions and rear ends out of is totally bulletproof, but the parts don't belong in my 928.

Default Gear oil recommendation

I'm going to open up the thread to a gear oil recommendation. What do you guys recommend for this application? I use Swepco 201 on the other cars. What do you think?

LSD box, by the way.

No religious style oil holy wars allowed, I know this is nigh on a religious topic!

Mobil 1 75W90. Does the car have a transmission cooler?

Default Cleanliness is close to godliness

Spent the past 4 hours and a spray can full of royal purple cleaning this trans. I hate filth, especially on engines and gearboxes. Can't spot an oil leak if the thing is covered in oil.

Now that it's clean, I'm going to take the torque tube off and reseal the box. There's some corrosion on the stub axles so I will remove those as well and see what the back sides look like and replate if necessary.

The rest looks pretty good, but I evicted the colony of spiders that was living in the trans webbing on the left side.....

+1 so true! Good job.

Sometimes you can save time by taking the parts to the local do-it-yourself car wash with a can of your favorite degreaser. Soak 'em down, then blast 'em!

Then back at the shop you can do the toothbrush-level final work. We just got in 6 engine cross-members to modify and that's what we did with them.

LOL, not in Southern California my friend! There isn't a car wash like that within 20 miles of me and making grease would be really frowned upon....

So the leak appeared to be down by the rear drain plug, and whenever I have a situation where there is a flat, thin sealing surface that doesn't seal, I don't automatically blame it on the gasket.

In this case, the gasket that holds this rear cover on is wafer thin, and I always hate to spooge RTV on there to fill gaps.

So I check it out with my machinist straight edge, and it's warped a bit. Hard to tell in the pics, but there is a good amount of light coming through the gap between the straight edge and the rear cover.

So I'll have to mill it flat. I'm using an end mill just to take a couple thou off and flatten it nice. Had the part been shaped differently so I could secure it better, I would have used a flycutter but an end mill will do just fine.

Tomorrow I'll mill it.

And it's milled.

Fits nice now, no gap.

There is a bit of a trick to doing these for all you garage machinists. I am by no means a pro machinist; I am self taught by books, videos, and practical experience. Even so, I learned a few things over the years.

Lots of times when you mill down valve covers, plates, or other flat objects that have taken a warp, your biggest challenge is not machining the piece, it is SECURING the work piece. I heard a great machinist once say:

"A new machinist will say, how can we machine this piece? A veteran machinist will say, how can we secure this work piece?"

When I was new at this, I would take a warped piece like this cover and put it on the table and torque the **** out of the clamps. Then I would machine it flat. Then I would release the clamps....

WTF? It's still warped! Machine it some more.

Wrong strategy. The clamps are strong enough to bend even heavily gusseted aluminum enough to alter the shape. Then you machine it, then it springs back.

This piece was secured only tightly enough to hold it flat and still, just a hair over finger tight....that's the right way to do it.

And I have lots of screwed up parts to prove I learned this lesson

Default Bananas

One of the things that allows the Devore car to fit such huge rubber is these custom banana arms Bob built. They are long enough to decamber the car nicely, and easily adjustable as well. Basically, you max out the camber eccentrics on the arms first, then don't touch them. After that, you adjust camber from here only. One easy adjustment spot.

The hardware on these arms was corroded and rusty, which is not good because a) it's ugly, and b) you need to be able to easily adjust these.

I took the arms apart, painted the bodies, and replated all the hardware. If you don't have a plating setup at home, GET ONE. Sending your **** out to be plated in one big bag and then getting it back not knowing which piece goes where sucks. For less than $300 you can zinc plate your own stuff at home. I have been using it for years.

Here you can see the refinished arm next to the unrefinished one. All threads coated in Liqui Moly for posterity.

Next up, the rear suspension comes apart. I will inspect and refinish every piece on the rear end, firstly to see what I have and how Bob did it, and second, because it's a race car and I don't want to leave anything to chance.

First thing I did was use the impact on the axle nuts to remove the axles. Was pleasantly surprised to see a generous coating of Liqui Moly on the axle shaft....it slid out with one little tap from the sledge. Thanks Bob, wherever you are.

Next up was removing the custom arms. They look good, just needed some cleaning. All delrin bushings, all in good shape.

Took the hubs off, and although the bearings seemed free to rotate, I am not taking the chance. Last 928 I owned I had to replace a wheel bearing with the suspension in the car....NOT fun. So I pressed the hubs out, then pressed the bearings out.

That circlip was so nasty I had to use the heretofore unused massive ratcheting circlip pliers

This all looks great, despite the fierce Calif winter it makes me think we should have some kind of OC get together maybe after the holidays.

Sounds great!

And I had to put on a jacket today to go with my shorts and flip flops!
