Dumb Question Thread - No Flaming Allowed

[Calb]

Looking to upgrade to led tail lights. What’s a fair price for supposedly mint lights from 2004?

Dont want to spam the dumb questions thread with my FCAB issue too much, but figured followup with pics of my findings. So; faulty install by my indy’s mechanics when doing the new LCAs last year (had the Turner FCAB installed by them prior that, ~2 years ago) OR had the FCAB just failed/broken?

Thing is i had seen that the passengers side had that crack right after the lca install but didnt think much of it… i didn't complain to the shop thinking it was just a superficial plastic outer piece and there was no noise or creaks at the time. I feel if it was broken before they did the lca install they would've said something.

Also I wasn't able to replicate the creaking sound with the front end in the air unfortunately.

Look like it broke right at the cast line

what offset would be ideal for a 18x9 wheel up front to run without spacers? have full adjustability with coils, camber plates, etc

Not really applicable to the E46 M3 but I haven't had any answers on the M5 boards.

The S85 (as does S65) has a bedplate that forms parting lines on either side of the F.M.S/R.M.S so when replacing these seals your are supposed to use a special prepping compound/adhesive.

It's about a $150 kit for the prepping compound,"sealant" syringe/needle/tool to push adhesive from syringe.

I did the FMS on my S85 recently and just smashed some Toyota FIPG into the parting lines and called it good.

I am now going do the RMS as part of a LW flywheel install but want to know just how important,or not, the use of the correct adhesive is.

I have the same issue on mine (not as bad), however mine are about 3-4 years old at least. I need to replace them fairly soon.

Yes in theory you should

Yes in theory you should

Agreed, I just wondered if anyone had any insight into what this compound actually is and if it can be substituted for something else.
That said it's likely not worth the risk of having to redo a RMS job.

We always use the bmw stuff. I have never looked into any alternatives

Same issue being that yours are cracked as well, or also have the creaking sounds too? Lmk what you end up replacing them with

Can anyone identify this part? Dropped the belly pan for unrelated maintenance and found it sitting in there.

One of the two hood lock assemblies. You'll want to figure out how it broke off and probably get a new assembly before driving the car.

Amazing. Thank you!

cracking.

so this picture is from last year and probably after 50k (at least) of driving on these. After rethinking maybe yours are failing pretty fast if they are only a few years old. This was daily driving and a handful of track days.

You can see a crack developing.


overall the car has done 50k miles (realistically I think closer to 60-70ish) on these and don’t squeak. They did however squeak for the first 500 miles or so.

i probably will replace them soon with new units as i love the feel… compared to stock. Don’t remember how the poly ones did in comparison

Do torque marks work for removing and reinstalling a fastener at the same torque?

Why I ask:
I've made a bunch of changes to my ride height. I was thinking it wouldn't hurt to loosen and retorque any non-sperical control arm bushings at the new ride height. The rear upper control arms won't fit a torque wrench with the diff in place now, I was thinking what I just mark it as it's properly torqued now then refasten with a box wrench to the marking.
