I bought a used rear diff (newest model diff) to replace mine in the 06 V, however, my diff had the bushing installed. I'm wondering if it can be pressed out or if it will get ruined?
The bushing has maybe 5k on it...

Also, should the pinion seal be replaced? I am already replacing the axle seals.
Thoughts on replacing the rear cradle bushings as well - they aren't part of the diff but jw

they're cheap. get another. better yet, go with revshift, which is a better design. unless you are short on cash, then why not re-use. you can always replace it later.

thanks for the quick reply HAMSTAR. Do you have the revshift one? it is pretty cheap, I might as well get a new one. Do you have the 80a or 95a?

No, I have the CS, but I like how the revshift design doesn't use a metal sleeve that can expand and contract with temp fluctuations.

I just installed the blue Revshift, and all rear end clunk is gone. I also replaced my driveshaft with a solid replacement (no bullshit rubber to flex). Some have reported the red to transmit more noise than before...mine doesn't whine, so no more nose than before.

Go Revshift, I put in a Creative Steel 2 months ago and am pulling it for a red Revshift this weekend. Only $50.

Side note, anybody know the part number for the pinion seal? Can't find it on my parts lists.. :mad2:

I ordered mine on Black Friday. It took over a month to receive. I don't think they stock bushings now...all built to order. Could be wrong, but I know people are still waiting a while when they order nowadays.

I'm having my rear end replaced under warranty, and I also had a CS diff bushing and the diff block. I also have to order a new bushing and block if I decide to stay with CS. Do you guys know if the CS bushing and diff block is still more effective than the Revshift stuff? I wanted to place an order this week, and I'm on the fence since I've heard pretty good things about Revshift.

In addition, I have UUC motor mounts and CS trans mount - I was also thinking about replacing the UUCs for Revshift or UMI. I was hoping to get some advice on that front as well. I believe the UUCs are in good working order, but I feel like they transfer way too much vibration through the cabin.

Careful with the trans mount... I only hear bad things from tuners and gearheads. It raises your trans a bit too high and transmits a lot of noise.

We usually keep all of our parts in stock and ready to ship but since the release of our CTS-V bushings on black friday we have just been swamped with orders. We are trying our best to get the stock levels back and we will get there very soon. We are hoping to be back on track in about a week. We will then be back to shipping orders out within 24 hours.

This is true if you are talking about the CS trans mount. Incorrect if you are referring to our trans insert. Aside from some people with worn aftermarket shifter parts, we have heard nothing but great reviews for our trans insert.

Revshift, can you comment on CS's differential bushing and diff block versus your differential bushing and rear cradle bushings? Do both product offerings aim to accomplish the same goal? Just trying to learn how your approach differs from theirs when trying to eliminate the clunk in the drivetrain. I have CS trans mount and CS diff bushing and diff block - I haven't had any problems with them and they eliminated the clunk. But my rear is being replaced under warranty and I plan on upgrading again. Just not sure if I want to try something new (your products) or stick to the CS bushing and block. Thanks in advance.

Cradle bushings have nothing to do with clunk. If you want to compare, it would be Revshift diff bushing vs CS diff bushing and block.

I would need the part in 2 weeks. If I order today, would that be possible?
If not, what is the estimated delivery time?

Absolutely. If you order today the wait shouldn't be more than a week. I am personally working 16 hour days this week to get caught up with everything.

Then why has my order from 10 days ago not shipped? Sent an e-mail to you tonight...

I don't see why you couldn't press out the old CS diff bushing. The stock one too. IF, you're using one of the press tools. I got my stock one out just find with CS's diff removal tool and didn't need the tool to put CS's in since it was very close to the size to go in.

FWIW, when I did mine with and without the block, the block made more of difference in drivetrain clunk/movement.

It appears that you already purchased from RevShift. so, test them back to back and report, um, back :yup:

What is true? raising the trans a bit too high and/or transmits a lot of noise?

Have you tested back to back against your products?
