New OEM diff bushings = no more clunk

330CI - Massive pain in the ass, but oh so worth it. The key are these mack-daddy tools pictured below. Car feels new again.

how much were the tools? did you rent them? do these also work on the front (smaller) diff bushings or just the one large rear one? How was the condition of the front small ones?

Rear = rear bushing only (~$125)
Front = front bushings only (~$125)

Purchased both from Amazon. Tools made by Kommen Tools and KTC Tools. Amazing quality, thrust ball bearings and all.

Front bushings were perfect, but if you're in there you might as well. The actual pull/push was super easy due to the tools. The hard part is dropping the exhaust and diff. Took me 6 hours start to finish, taking my time.... but what a biitch. I've dropped the M3's diff before so I wasn't a total noob, but still.

Oh - we also installed the M trunk lid spoiler Looks tits.

Yes, after shipping, etc... you're looking at ~$275 to your door for both tools. Still far less than having a pro do the work, and any excuse to buy new tools is cool with me. Plus I hate paying for labor.

Where you at in SoCal?

you're right. those prices aren't bad. i may go halves with ///mpr77 (mike) he wants to do the same job. I'm in LA/West SFV

That's incredibly cheap compared to other kits i've seen. I wonder if they make kits for the rest of the rear control arm bushings (not RTABs) back there? all 8.

Pretty sure they do - go to their respective websites and you'll see all kinds of BMW-specific bushing tools. Subframe, CAs, etc.

The best part is that these tools are, IMO, super high-end professional grade.

I can't see the model#s too well on the pics. Can you edit the original post with the manufacture and model# of the tools?

You may want to clarify that in your original post. Makes it sound like you got rid of the M-clunk.

That's good enough. Thanks a lot. Which bushings did you install in the 330? Meyle HD? OEM?

Not a fan of Meyle... quality is not OEM/Lemforder IMO.

I installed dealer-sourced OEM bushings.

For as something as PITA to replace as the diff bushings, I'd probably do OE or OEM as well since the Meyles are too new and unproven (if you sourced from a dealer, they'd be OE, not OEM)

Was lowering the rear section of the exhaust from the muffler hangers sufficient or did you need to completely remove it?

Good call on the "OE" indeed. Only the best

On our '01 the exhaust is a single unit from the headers to the tips. Entire thing must drop... fairly easy. I'm sure others have "shortcutted" this repair, but I'm too old for that. Just have it in your mind to "drop exhaust and diff" and the job is fairly straightforward.

so i'm assuming you got new gaskets for the exhaust? I guess that's why you describe it as a major pita

Reused the gaskets - they were perfect.

I call this job a PITA because dropping a 90lb diff on your garage floor under the car is a biitch. The worst part, honestly, are the 18 diff/half shaft torx bolts. You have to wrestle with every single one. You'll see what mean
