I was thinking the holes in the rotor were threaded, but I guess not. I drilled out the broken bolt (which took forever) and tried to use an easy-out and the easy-out broke off. Tried to drill out the easy out (which is even harder than the bolt) and the drill kept getting off-center. Finally gave up and decided it might be easier to just replace it. I looked in the Bentley manual and I didn't think the write-up was all that clear on how to do the bearings. I was looking rear brake drawing here: (http://www.unofficialbmw.com/e36/brakes/e36_lets_brake_it.html) So in the part labeled "9" (disc), those are just pass-through holes and not threaded correct?

Described as a grown-up's WRX (at least in the style department, performance still "too fast too furious"). Pricing similar in NC than to CA. Of course another friend just got a '99 A4 2.8 Quattro and it is one 'smoove' ride. He was smart enough to get the aftermarket warrantee. Shifts like a dump-truck, but that might specific to this car/driver. -Jonathan 95 M3 92 miata

I don't know there's a specific issue with them, but they will wear out over time. '95s are getting to be 10 years old (impressive math sKiLLs eh?), so I would guess that they would begin wearing out. I replaced the coils on the '93 325is ~2 years ago in the course of tracking down a cutting-out problem. Wasn't the coils, but I did notice a slightly smoother idle, so <shrug>. > If you had to replace them what/where would you buy from? Are the > aftermarket ones any good? I got mine from Bimmerparts.com. I was told to be sure to replace them with the same brand as are in the car originally (Bosch or Bremi), as there was some issue with coil/DME compatibility. This is unconfirmed, but I'd rather error on the side of caution.

Correct. The lugs screw into the hub, passing through the rotor. > Any write-ups on how to change the hub? I'm sure someone does, maybe Neil Maller? (His front hub write-up is on the same site you reference above - Ron Stygar's page at Unofficial E36.)

Broke a stainless bolt that holds the disc to the wheel. Then broke the easy-out. I finally used a very expensive (although cheaper than a wheel) cobalt drill bit. Forget about titanium. The cobalt bit went through the bolt and the easy out. You might give it a last try.

Date: Thu, 21 Oct 2004 14:32:31 EDT From: KResener@aol.com Subject: Re: [OT] Used Audi A4 2.8 Quattro I'm a big fan of Audi. Think they're a close second to BMW in build quality. What they lack in excitement they make up in the benefits of quattro. My wife currently drives a '97 A6 quattro wagon with 125k on the odometer. Car is still rock solid and I wouldn't hesitate to jump in it and drive across the country. I just replaced the catalytic converters, and last spring the rear tranny seal went and those are the only two issues to date. Better knock on wood so I don't jinx myself.... Since I have the M3 for excitement, I'd take an Audi over the Subie any day strictly for safety and build quality. Don't get me going on the Camry, surprised you even admitted it....! You may also look into a used e39 five series. '97 and '98's have really come down in price. Kurt

At the end of the day, the quality of an event varies dramatically according to who is running it. There's quite a lot of variation geographically even within clubs. Sad, but true. - Mark, thinks GGC and Audi NorCal run excellent events

The rotor has holes and that's it. Not only does the rotor have holes, they are clearance holes to boot! Absolutely no lug thread engagement. There is one fastener that attaches the rotor to the hub, both front axle rotor attach and rear rotor attach is the same, one fastener per rotor. The wheel 'traps' the rotor when fastened to the hub. Go here < http://rust.mine.nu/bmw/ > and bore in to a picture of the rear hub/bearing < http://rust.mine.nu/bmw/partgrp.do?model=BF93&mospid=45245&prod=19941000 &hg=33&fg=40 > .....Why don't you try extracting the broken bolt and tapping the cross threaded one? I'd try this route as a first measure. Then replace the hub as required, per Chester recommendation.
