I would use some of the 3M spray adhesive that they sell for 'landau tops'. Holds very strong, only needs to sit for a few minutes before its 'ready', and holds up to very high temps. I forget the number that's on the can, but you should be able to track some down pretty easy. Dave

So. I finally decided to tackle rebuilding my steering rack since it leaks like a sieve. I toyed with the idea of getting another remanufactured rack from BMW (~$600) or source one from a junkyard (~$100 - $200) or just rebuild my current one. After going back and forth and back and forth and back, and then forth. I decided to attempt to rebuild my current remanufactured rack. I would have bought the special tools (a bunch of different fittings to make pressing in and out seals/bushings/bearings easier), but my local dealer told me that they are NLA. Ugh. Wayne and I thought we could perhaps get away with using sockets and other creative ideas. So out came my rack and that old Wurth brake and parts cleaner is awesome (THANKS MO!). Without any effort at all, I held the rack over the garbage can and spray the cleaner onto the housing.the thing looked like it was brand new! Of course, it helped that the rack was a reman and didn't have that gunky cosmoline all over it. Anyway, we hit a number of obstacles.primarily that we didn't have the special tools.ugh. So my car was on the lift with nothing to hold the front wheels together. Something had to be done.called a few dealers. One dealership had it in stock for $800 (plus the $170 core fee). Um...Better check junkyards. Managed to find a rack from a '96 328i somewhat close by so we picked it up. Upon returning the garage, I cleaned it up and went through the normal procedures of checking it out. Earlier, we measured the steering of my reman unit that was currently on the car. It was 3.5 turns lock to lock. I did the same check on the '96 rack and was taken back.3.125 turns lock to lock! If you remember a while back, I managed to measure the ratios of a bunch of reman racks from the '95M3, '96+M3, and Z3. All of those racks measured out at 3.5 turns. So it would appear that the remans have a generic ratio that suits all the E36s (Z3 included). So now my curiosity is piqued.. How many turns from lock to lock is your car? People have always said that the '95M3s were quicker. But I have yet to validate that! Shoot. I should ask the Z3 folks as well... Anyway, looks like I'll be proficient in rebuilding steering racks by the time I'm done. An interesting observation was while squeezing the boots that cover the tie rod ball joints, I could hear air squishing by. There is a center seal that separates what I think is where the hydraulic fluid should go and where the rack and pinion mesh. It is my belief that where the rack and pinion mesh should be devoid of steering fluid and only have grease. Oh well. Thanks if you can provide some info. Chester

Michael, I've had this same problem and can only tell you what has not worked very well for me: 3M weatherstrip adhesive and contact cement. With either you're going to have to be exceptionally thorough in your coverage of both mating surfaces, work quickly, and somehow ventilate the heck out of the interior of your car while doing so. I've done this two or more times and each attempt has only proven to be a temporary solution. Please do let me know if you are able to improve on my results.

Are the pads wearing evenly or is there a wedge shape to the remaining pad material. If so, it's either worn out guide bushings on the calipers or worn out wheel bearings. I go through approximately two sets of fronts to every set of rear pads using Hawk HT-10 F&R. If it's only me driving the car that's ~8-10 track days.

Unfortunately, in that last off track excursion because someone dumped coolant all over the track, my rack (the faster one) got bent. DAMMIT! So now I'm on a reman again. Shucks. > Anyway, looks like I'll be proficient in rebuilding steering racks by > the time I'm done. This still hasn't happened yet since I don't even have the time or space to research all of this. The real problem becomes why is one's rack leaking.. If it's because you bent the rack, then you're SOL. If it's because a seal went AWOL, then it might be salvageable. How does one offer a service to repair other people's racks when you're not sure if it's scenario #1 or #2. If it's #1, I wouldn't want to get into the whole he said/she said of no, my rack wasn't bent/yes, yes it was... Other than that, it's a pretty straightforward rebuilding process if the rack isn't bent and you have the proper tools (which I'd have to design). Chester
