Hey Steve, I would try White Lighting lubricant before disassembling anything. It is available as an aerosol and penetrates the smallest spaces very well. It should be safe for Delrin and has done an amazing job on some issues my car has had. I am going to try it on my RTAB shims next. You can get it at any bicycle shop. -- Rex Tener rex_tener@yahoo.com

Steve, I'm with Zack on this one and would suggest checking other sources for the squeak. I'm not an engineer either (but that never stops anyone from offering an expert opinion does it? <g>) but anywhoo, I thought Delrin has some sort of self lubricating property about it so lube is unnecessary. I would not tamper with the tight fit that you have now. The control arm is not supposed to spin about the bushing as per the stock rubber parts that "bond" together in this location. That's probably a draw back of the delrin bushing but the benefits IMO outweigh that. I've never considered the delrin c/a bushings to be a street car part even though I drove my E30 M3 to and from events with them on. Then again that little devil was so loud I doubt I could hear squeaks from the suspension and I always kept the urethane sway bar bushings lubed up (I used the Energy Suspension ones with the grease fitting). -Carlos.

Thx Stefano -----Original Message------------------------------------------------------- From: Gaudio, Stefano Sent: Thursday, December 09, 2004 5:22 PM To: 'E36M3' Subject: Best way to store an M3 Here is the dilemma. For the winter I'll be driving my "spare" car a '97 Nissan Maxima SE 5spd (nothing great but it'll get the job done). This means that my '98 M3 will be sitting pretty with snow shoes in a heated garage waiting for warmer weather/temperatures. NOW the question: Should I drive it once in a while to keep everything in working conditions (battery, fluids, brakes) OR Should I NOT since that once every 1 or 2 weeks start up will accelerate engine wear due to the lack of initial lubrication since close to no oil will be on the engine walls? But then again no start-up for 2-3 months (that's all I can last w/o her) will make a really dry start-up with even worse engine wear? What to do? P.S. It has snow shoes on because I was planning on driving it all winter long, but the winter Maxima seems a better idea.

Just out of curiosity is this a race or a daily type driver? I passed on delrin because of the non-compliant nature of the material when I did my suspension a few months ago. I was told that unless I wanted the extra noise from the wheels transmitted directly to the body and inside the car to "stay away" from the delrin CA bushings. I went with the urethane instead. I notice a little more noise but not much. So, just a thought, unless it's a race car I suggest going to something softer than the delrin.

I have the delrin offset as well but it did not squeak but it creaked making a kind of snapping feeling in the floorboard. I tried synthetic moly grease and like you said, the fit is sooo tight it only lasted a couple weeks. I went down the spline path. Used a hack saw to cut splines from front to back through the hole. About a 1/16" apart about 1/16" deep and filled them with the same grease. Ran them this way for the whole season this year (about 15 track days) and never heard from them again. Will be interesting to see how they do next year. So far still tight but silent. It also looks like bimmerworld is carrying a new bushing/carrier kit that has a lubricated bushing as an alternative if it gets bad enough..... --Bill 96 red M3 Boston

#6. Clunk from the front, squeak from the back... - from Som Naderi
Top
Date: Tue, 14 Dec 2004 10:58:30 -0800 From: "Som Naderi" <som@dimensionracing.com> Subject: Clunk from the front, squeak from the back... So, it's been a little over a month now that I've had the H&Rs in. (btw, why are they called coilovers if, well, the rear springs aren't over the rear shocks? am I missing the definition of "coilovers"?) At first I was THRILLED with how solid the car felt, but a little disappointed with how rough the ride was. As a couple weeks (and about 500 miles) have passed, the rough ride has mostly gone away and the tight handling has remained -- I'm VERY pleased. However, I still have a couple issues/questions. 1) Before the install, the left rear had some squeaking issues (getting in and out of the car, jacking the car, setting it down). Now, both sides squeak. I replaced the stock RTABs with Powerflex bushings and I anti- siezed them before I put them in. Could these be the issue? I basically figure it's one of 5 things, and I'm curious as to what people feel is the most likely culprit (given the minimal details): - RTABs - upper control arm bushings (or are these bearings? whatever's stock...) - lower control arm bushings - sway bar bushings - springs squeaking against the upper rubber perch (or the rubber perch squeaking against the body) 2) I've pushed the suspension to about 70% at this point. The front feels fine going through turns -- doesn't feel sloppy or loose or anything. However, when the car goes over very quick/deep bumps (small potholes, respectable sized cracks in the ground, etc) there's this loud clunking sound from the left front (and a little from the right). I'm fairly certain everything's tightened to spec on the stuff I swapped out --H&R coilover struts and KMAC camber/caster plates. I've got roughly 3mm of clearance between the tire and the lower spring perch on the strut, though I don't think this is the problem. It sounds like a metal-on-metal clank. Any ideas? Could this be a result of worn control arm bushings? The front sway-bar mounting bushings seem worn, and I've been meaning to replace them, but could these have anything to do with it? (I doubt it, but I figured I'd throw that info in) Another piece of data would be that the clunking tends to be louder when I'm turning while going over said potholes/cracks. If I hit them straight on the clunking is still there (and significant), just not as loud. Anyways, as usual, any and all help would be greatly appreciated! - Som

Nope, that's not it either. The one on the passenger side of the radiator is the dual temperature switch for the auxiliary electric fan. The coolant temp sensor used by the ECU is on the intake side of the head, right at the front under the top engine cover. There's a photo in Bentley on page 130-18. Neil 96 M3 - Bastard child

#9. BAD BAD BOLT!!! Somebody help... - from Gaudio, Stefano

Date: Tue, 14 Dec 2004 16:11:35 -0500 From: "Gaudio, Stefano" <Stefano.Gaudio@NERA.com> Subject: BAD BAD BOLT!!! Somebody help... I replaced my front rotors this w/e on my e36 M3 and came across a bolt that just won't come off. It's the locator bolt (see fig 6 on http://hock.net/m-rotors.php ) on the driver side. It's supposed to be torqued to 12lb/ft but it's more like 100lb/ft+. Not sure if it's due to the fact that being on driver side it tightens ever time I accelerate or just the fact that it may be corroded but my 6mm hex key has lost most of the grip (the inside of the bolt is about to become a F... circle). I used wd40 and a couple of other penetrating oils tapped it to have the metal vibrate and loosen up but it just won't give. Anything else I should try before drilling the sucker out? I really rather not!
