1LE differential bushings

[i2disturbedSS]

Im getting a 1LE differential soon and was wondering should I replace the bushing while I have it out with poly or solid?
I've researched some and read almost half and half as far as to replace them or not. I've also read that the 1LE differential has different bushings then the regular SS and do not necessarily needs to be replaced. Is this correct?

They're the same bushing, I've removed both. They will add noise, and depending on the diff it can be a lot. Personally I wouldn't on a street car that doesn't have a ton of power. I did on mine but it's 80% track, 20% street not vice versa.

You may be thinking of the cradle bushings which are a bit stiffer but still not great.

Diff bushings can be tricky because they can add noise but it 100% depends on how the gears are set up. Even with stock gears its like a box of chocolates, you never know what you are going to get. You absolutely do not want to go full solid. Your best bet is the BMR poly/delrin combo set. They use the hard delrin bushings in certain spots to resist movement and the softer poly bushings in others to minimize noise transmission.

How do you plan to use your Camaro? Drag, road course, AC? Do you plan big power upgrades?

Thanks for the replies.

Yeah just a few bolt-ons, with about 10% of track time for now. Hoping to do more within a year or two. So in your opinion not worth it, just use that money for gas pretty much?

Cool I don't think I've seen this set mention.

All but the road course so far. Plans of a cam and stall, no FI.

Also, I may only had wheel hop once at the drag strip. So wheel hop is not an issue right now. Im more wanting to put the power to the ground and making good use of the 3.91s

Iam looking at LSR trailing arms. I might have to make another thread on that subject later.

There's far better places to spend money if you're worried about wheel hop with none of the noise. There is zero reason to run poly let alone delrin in your intended use. Do trailing arms first and get a good alignment, you won't get wheel hop in 90% of cases.

Thank you. I have seen a lot of your helpful posts in similar threads.

This. You will get a lot more bang for your buck with trailing arms and rear cradle bushings.

The OE differential bushings will work well for you.

Off to do research on trailing arms

Do yourself a BIG favor and install a set of Hendricks Engineerings Delrin Offset Bushings while your changing differentials.

Not only will they correct the excessive drive shaft angles that the car was designed & built with, they will stop 99.9 % of the wheel hop!

If you do not believe me on the drive shaft angles, drop what you are doing & go out & take a close look at your Camaro for your self. Installing the offset Delrin bushings from Hendricks Engineering will allow you to lower your Camaro up to TWO INCHES, that's right I said TWO INCHES & launch a STOCK SS Camaro with 430 hp. hard from stop lights with out breaking the drive axles! Ask me how I know this!

I installed them in my 2010 SS/RS when I recently installed a Ride Tech Level Two coil over suspension & it was the smartest money I have spent on the car thus far! As far as I am concerned, they are a NO- BRAINER!

As far as NVH & the dreaded gear whine that you here so much about when using Delrin bushings, the only time I am getting gear whine in the car is above 65mph! The faster you are above that the gear whine will change to a higher pitch. It really is no big deal. If you are worrying about some gear whine in the car, you probably bought the wrong car!

A little gear whine in the car is a small price to pay for the added benefits you will get not worrying about breaking axles! If you have ANY questions installing them, feel free to pm me any time.

You need to order them from their web site direct, or just give Thomas a call direct & he will get you taken care of in short order.

I have attached a few photo's of the bushing installation.

All the best,

Gear whine is a variable differential to differential. Some are quiet. Some are not and some scream like a jet engine. Looking at what the OP is doing, they should be fine with the OE bushings.

I will look into this thank you.
