So the last time I drove the E30 there was some noise coming from the rear of the car.
I decided to replace the rear upper shock mounts so I ordered those with new seals as well. On the Touring model you need to remove the rear boot trim and acces the two nuts through a couple of openings while making sure you don't drop one into the cavities :)

The old ones still looked good, I did replace them while I had everything apart. In the end I adjusted the rear tailgate catch a little more and took the car for a spin with my brother in the evening.
The squeaking noise is gone but there is still some ticking kinda noise. hard to explain and hard to replicate without driving the car..

I also send a couple of request to get samples for new headliner material. The foam on between the hard shell and fabric deteriorates and lets go of the fabric. Which causes it to sag down.
The first two samples I got at the top were too brown/beige. But I think the one on the right might be the closest to the original. I still need to compare by holding it against the original headliner.

Looking good! E30 road trips are the best. I have a ~1,500 mile (~2,400 km) road trip coming up next week.Leave a comment:

So I've been able to test the steering rack for a while now and the weird feeling I got on center if fully gone! Had I known before, I would have just used the original bushings the first time around..
Last weekend my girlfriend and I spend 4 days at the Belgian coast, I decided to go with the E30 as the weather was pretty good.
Feels great to drive it again, I should drive it more though! However I did notice some squeaking and screeching coming from the boot.
At first I thought it was the tailgate itself that was moving as I did notice previously that the plastic trim is touching the tailgate a little. I used a small cloth and put it between the two to test if that would be the cause but that didn't solve the noise.
After coming back from a drive, I shook the car at the rear and could hear the noise as well, I think it might be the rear top shock mounts? The noise it mostly only noticeable on rougher roads.
There are a few other things I need to do as well, like replacing the wiper stalk back to the airbag type one so it comes more forward as it's now a little too far away from the steering wheel.
However as for the SWRA /turn signal stalk, I might have to bend that one since the stalk also pressed in to operate the SWRA function.
Before, nice and clean...
After, not so much

Really wish I had some kind of formal training on the lathe, my knowledge is just off trial and error and sometimes there is a lot of errorLeave a comment:

The new seal for the steering rack arrived just in time on Friday at a local pickup place not far from work. So I was able to get it and start rebuilding the rack.
Previously that week, I stayed a little longer after hours to make a new tension plug for the steering rack. On the old one I stripped the hex nut when first disassembling the rack, I later made a little adapter to use the reinforcement ribs but these also started to deform so I decided it was best to start over.
It has some weird thread, M40,5 x 1,5. Yes 40,5mm... I dunno what ZF was thinking lol
Anyway, I used a thread micrometer to measure the original piece and new piece so the threads were identical. As I couldn't try the threads while the piece was still on the machine. Luckily everything turned out great.
Piece on the lathe, it's been a some time since I manual threaded on the lathe, probably from the time I was still in school. The threads were a little rough as I was turning pretty slow, I should have used a little bit of oil as well..
Piece clamped in the rotary dividing head to mill the hexagon shape (17mm)
Quick fine sandblast to remove the machining marks
New seal, Corteco 15019947B if anyone is wondering
Steering rack assembled. The old 3D printed clips I used got deformed over time, if I remember correctly I printed these out of PETG.
The new ones are ABS, hopefully they last a little bit better as I couldn't print ABS at the time.
Everything torqued back and fitted into place.
While the rack was out of the car, I adjusted the hydraulic lines I got made as well, as I noticed they lightly touched the CV axle.
Looks like I do have a little bit more room now; it's still close though
While I had the printer fired up to print the clips for the hard lines, I also modelled printed a little cap for the Girling brake reservoir as I was missing mine.
(I previously used some kind of grommet that fit snuggly over the cap but this looks a little bit neater) I might print a black one as this was just a test piece - red adds +10HP right?

I (finally) managed to remove the X3 steering rack I placing into the iX, it's been fitted for 2? years now. damn time flies..
The reason I wanted/needed to remove it yet again, I used a cheapish (it was the one kit I could find at that time) rebuild kit to reseal the rack.
I used the new guide bushings from the kit but they were a bit too tight causing the rack to have a sticky feel. Especially noticeable when driving in a straight line, I had to keep adjusting the steering wheel to keep the E30 in it's lane.
By now removing the rack, I could have a feel for the stickiness of the rack when turning the rack with a vice grip.
Oh wow, I can tell you it's sooooo much more enjoyable with everything nicely zinc plated and being fresh.
I was able to get a engine hook/bridge to keep the engine in it's place
And the rack disassembled, the plastic guide bushing is seated in the steel sleeve that still on the axle of the steering rack.
In this same sleeve there is also some kind of oil seal but with an extra nylon/PTFE ring to align the shaft better. In the end I did found the correct part number and got it ordered.
I also plan on making a new plug to adjust the tension on the rack. The first time I tried to loosen this part, I pretty much stripped the hexagon that's on this piece.

Not a whole lot has happen since last time. I did drive the Touring to the Belgian coast with my girlfriend and had a drive over there. It felt great driving it again.
However I did do quite a bit of work on my uncles E30's.
His iX Touring came in for a service as well as replacing the timing belt as it was just passed 5 years. I changed the waterpump, thermostat and some seals as well.
Valvetrain adjustment done as well
Next up was his Baur..
This one needed quite a bit more work, he wants to drive it the the South of France this summer. I did a full service, timing belt + waterpump, all new coolant hoses + vacuum hoses, new flexible brake lines.
I stripped the nut on the both sides of the front brake lines so I had to make new ones. The exhaust was renewed too, last time he drove the car it broke at the front of the muffler. I did need to adjust the exhaust hangers quite a bit as they didn't fit all that great. There were quite a bit of electrical gremlins too, I had to replace the central locking module, replace the SI board batteries as well as fixing a couple of traces on the PCB of the cluster as they were broken by using screws that are too long which damaged these.

Yeah, I'm just over 2meters (203cm). I felt like the K2006 is pretty much like the Mtech 2 wheel I had..
Not a fan of those deep dish wheels as well especially for a street car.
If you really are interested in those L2007 hubs, I could always forward the steering hub on Ebay Kleinanzeigen to you if the seller doesn't ship to the US..
Because of my height, the sport seat is all the way back (to have room for my knees/legs) but I found that I had to stretch my arms too much to reach the steering wheel. It's pretty perfect now with this hub. How is this for you?Leave a comment:

Thanks! Yes, I'm 6'5" (198cm) tall. The K2006 hub is better positioned than a stock steering wheel and appears to be 3.4" (8.6cm) in length, so the L2007 would give me just over 1.3" (3.3 cm). I could install a "deep dish" wheel, but I'm not sure I like that style. There may also be an option of extending the current K2006 hub with a quick release setup, but I still need to research that.
Oops, you're right, I messed up the type of hub and the lenght.
K2006 (short) 8cm
L2007 (long) 12cm
Indeed, you can't seem to find these L2007 hubs as easily (I'm pretty sure they no longer make these long versions) I was lucky to stumble upon one in Germany (Ebay Kleinanzeigen), just had a look and there are 2 more for sale as well..
You're also pretty tall right? Also having trouble with the K2006 hub?

The steering wheel and cover look great! I just installed a Momo Prototipo 350mm wheel with their 2006 hub. I can't seem to find the L2007 you're referencing. Do you have a link (and will that fit any E30)?
Also, how long is the L2007? I see you said 80cm, but that's over 31 inches so I'm guessing it was as typo.
Awesome work as always. Thanks!Leave a comment:

Had some time this weekend to fit the new hub and steering wheel, had to sand the 3Dprinted cover a little bit and readjust the plastic steering column trim since the cover was slightly rubbing.
Happy with the result and fitment as well, couple pictures :)
I might cover the plastic with some vinyl but kinda like the look of the printed part as well, not sure yet
