No i dont but its not diff movement, I can rock the drive shaft connecting flange back and forth with my fingers.

On the one piece driveline you can move the flang back and forth? What happened to solid mount type?


I ordered this for the diff.

If differential bushings fix this problem how did this take over a year to figure out lol

Most people are stingy when it comes to trying a solution. I said fuck it.

I am not sure it's a cure all, but it will help by tightening up the driveline. I do believe you will be exchanging one noise for another?
But better performance

It for sure cures the thud, the NVH gained is SUPER minimal.

I have both the BMR cradle lockout and differential lock out and I still get that thud every now and then

Thats pretty weird.

Glad you're happy with our differential bushing inserts! Keep us updated on the wheel hop reduction!

You guys should market this item as reducing the thud. I would have impulse bought this item the day I drove home from the dealership if I knew there was a simple fix.

Installed the MGW yesterday. Part of installation is to slam into first to check rear lock out alignment. I don't normally do that. Normally I shift like the fellow in the video above, and I don't hear a thud. But today I was probably forcing it in to test the MGW out and heard the thud 3 times or so. So I think it's possibly related. I don't know if the diff bushing inserts will help but I have Steedas (installed the rears a few weeks ago, haven't gotten around to the fronts. Will give it a try over next weekend,probably.

I'll probably upgrade the entire drivetrain before giving up on this car. Until I can do all that I'll live with the rattles

How much better is shifting w/ MGW? Easy install?

Damn, I was hoping that would cause the thud to go away. I'm still getting this shifter though!

It's a significant upgrade in build quality. I suspect the big difference will be with high RPM shifts. I drove mildly around some twisting roads at around 3-5k and enjoyed the car immensely.

I would not say it's easy to install. It's doable with the right tools, some decent skill and a lot of patience. Had back spasms under the car three times. Should have stretched first, for a few days.

Yes I hear you....it's a really nice shifter.

Installed BMR cradle lockout and Boomba shifter bracket while I installed my springs this weekend. Feeling/hearing the thud is reduced but still present. Can still make it not happen the usual ways everyone already knows about though, IE holding in the clutch for a few seconds before hitting first from a stop, and if you're slowly moving forward like on a decline when hitting first it doesn't happen. It didn't bother me before too much, so it really doesn't bother me now. The notchy 1-2,2-3 shift when the trans is cold bothers me way more.

I have the same clunking going in with my auto. (I have steeda IRS braces, diff bushings, subframe bushings) Was under the car last night working on the exhaust and the amount of slop in the factory drive shaft is crazy. But what concerned me is the amount of play at the transmission. Almost felt like there was slop in the output shaft. Guess before I install my 1 piece driveshaft I'll have to make the dreaded trip with my modded car to the dealer. Because I'm sure if I roll in there with a carbon drive shaft the driveshaft will be in the issue. LOL

Do you race your car often? I'm asking because I would like to know the benefit of upgrading those bushings, braces, and driveshaft on a car that'll rarely ever see the track, like mine. Did you replace those just because these new gens have softer, sloppier parts?
