I did a track school (Laguna Seca) in an E36 M3 in the rain with the Sumitomo HTR Z tires. It is actually pretty amazing how well even low-grade performance tires can stick in the rain. I didn't go 100%, but about 80%+ on the entire track. No crashes or spin outs. The nice thing about the 2.0...

As soon as I saw the broken spark plug insulator... "Excessive boost packs more air and fuel into the cylinder. If the fuel octane is too low, the ignition timing is too advanced, or the air-fuel mixture is too lean, the mixture will explode violently instead of burning smoothly. This creates...

As an option, I believe you can code out EDC on most BMWs. I did this on my 435i. Labor would be about an hour. I used VT Motorworks in Pleasanton.

Thank you sir! That's a good observation too. If there isn't enough grease to the sides of the bushing also, it just gets stuck. So it can't do it's job against the steering rod/arm it's supposed to provide tension on/to. Appreciate the write-up above!

Hey, did you just tighten it or removed the cap, added grease, and put the cap back on? And what mileage and year was your car?

Thanks B!

Yep. I did the same thing. I added the master brake brace. It's crazy how much noise that stupid bushing makes! Glad you got it fixed!

Ha ha ha. Ok in my defense, my mobile app/browser not showing location! :D

Sorry this took me a few days to reply. Aside from the asterisk grooves in the bushing, there's no grease channel. At this point, the only way to get this bushing is from a wrecked Supra or MAYBE from BMW as I assume all the new 2020+ Z and 2-3-4 series cars use the same rack. FWIW, I've...

What city and state are you in?

Ha ha ha. I get you. It is a PIA job. You will spend more time removing the splash tray (I think 2 dozen bolts than doing the actual service). But worth the 2 hours (remove and grease) because that bushing is not offered as a spare part yet it seems. And the added bonus, it'll quiet the...

Yep, fuel is my first thought. But like its been said, need a scan to narrow or pinpoint culprits.

No real torque spec as the cap serves as a spring tensioner against the bushing to steering rod. I've done this twice rack bushing twice (BMW and Supra). Essentially mark where it is now and replace flush with the rack housing. Take short drive. If too loose, tighten cap 1/16 turn clock-wise...

Thank you brother! 85km is about 53,000 miles.

@Branflakes123 - Kudos to you brother. Let us know how it goes. I super hope the F30-style bushing works just as well!

Hey guys, I’ve been chatting with a member on this board who was asking about the steering rack bushing. He just pulled his, and it looks like the attached photo. This bushing looks REALLY WORN. 86k miles from a 2021 car. (Thank you B!). The steering rack bushing has been a known issue with...

My 2022 was clunking like mad at 25k miles. I swapped out the ceramic pads (as they rattled a bit) and replaced the upper and lower control arms (massive deflection). Noise persisted. But I found a thread on this forum and a guy mentioned he was chasing a clunking suspension noise. I pulled...

Yeah, A LOT more worn looking than mine at 25k miles on my 2022 Supra. I've spent a good 15-20 minutes online trying to find other Supra and BMW Z4 guys who pulled the bushing and added grease as well as part photos. No luck. The issue is so new, there's not a lot of info about it. I found the...

Ooof. I just did mine a few months back. I didn't think to take pictures. But the one on the left looks REALLY worn down!

Yep, oddly the F30/f32 ones work.
