The driver's seat rocks backwards & forward and squeaks when I drive. Very annoying.

Since I had my son helping today (strong back and all that) I had him help me pull it from the car so we could see if we could tighten it up somehow.

Image

Sadly, it just appears to be old/worn as most of the play is coming from joints like where my son is pointing in this pic. We could not find any obvious location where something could be tightened down.

Image

Anyone have any experience tightening these things up?

This may accelerate my search for a set of E34 sport seats...

There are pins (for lack of a better term) that tie the sliders to the actual seat frame. Both they and the holes through which they pass wear. I might be weird but I never really noticed that on my car.

Yea, that's what we discovered.

On my car the rocking is pretty noticeable and most of the squeaks I get over bumps is coming from the driver's seat frame. Annoying unless the music is cranked.

My last e28 rocked pretty good in the driver seat. It was quite annoying, however, I didn't get any squeaking out of it. I'm putting e34 comforts in the zinno. I expect they have a few years left before they start rocking on me...

Wheels are being shipped by the seller today. He called me yesterday after I sent him an email letting him know that I'd be willing to pay him a little extra if he went overboard in packing them up safely. He described how he's packing them for shipment and I'm no longer losing sleep over it :-).

Tires (Conti DWs) are inbound to the place that mounts/balances wheels for me. As are a set of aluminum hub centric rings.

Vlad will be wearing new shoes RSN.

Interested to see them!

PS: Just was looking over your OP in this thread. Our cars were produced the same month. Mine is just shy of 2 weeks newer. 9-22-86 build date. :alright:

I'm tall enough to drop my seat adjustment all the way down when driving. It doesn't rock when in that position. You might want to give it a try.

That's probably what it was then.

Not only was my seat all the way down, but I took the feet out so it sat lower yet. I actually fit in that car with a helmet. A feat I haven't accomplished in any other BMW.

On the way in to work this morning I tried that and sure enough it stabilizes things.

I generally always run seats as low as possible because I got it in my head ages ago that it positively impacts lowering the CG of the car. At 6' I never have had a problem seeing over the steering wheel.

The problem is I need the front raised a bit for it to be comfy for me...otherwise my back is strained (I have a bad back). Maybe I'll see about shimming the front mounts up an inch or so as a temporary work around.

I've always wanted to drill out the hole and try a brass bushing to tighten things up, but never was motivated enough to take the measurements and locate a properly sized bush.

I looked at it pretty carefully and there's a lot of complexity in the mechanism. I immediately concluded that it'd just be a ton of work and probably not worth the time.

All you need is something that fills the hole snugly but still allows the mechanism to pivot without binding.

Bad news: I bought the wrong brake pads for my wife's 135i so the brake job is stalled.

Good news: FedEx just dropped off my 'new' BBS RX wheels!!! The seller did a great job packing them and they are in great shape. They'll get mounted on Monday.

Baked on brake dust on wheels can be a bitch to clean off...

... if you don't have a steam cleaner:

Interestingly only the left front wheel had it.

Nice choice of period-correct wheels. They should look awesome, especially with the car slightly lowered.

Now, how did I just KNOW that you had a steam cleaner lying around somewhere? ;)

It's news to me that the BBS RX are period-correct to the E28 -- I would have pegged them more as early-'90s wheels. In any event, I agree that they will look great on this car, period-correct or otherwise.

The RX is one of my favorite wheels. I'm looking forward to seeing them on the car.

It's fun knowing the provenance of a car. Thanks for the kind words. I'm quite happy with how it looks. The 17 year old in me wishes they were 17" wheels and it was 1/2" lower. But the 46 year old in me loves driving it every day on the rough streets around here.

I think a recent article in Car & Driver, comparing the new GTI to the Focus ST summarized it well:

"Part of being an adult is knowing when not to overdo it."

I was in Seattle all last week - was hoping to see this beauty prowling the streets. I would have pulled a "Counts Kustoms" and pulled up next to you saying "Dude, got a minute to talk about your car?" :alright:

She's looking great on the RX's.

Dropped by a muffler shop this morning and had them take a look at the exhaust alignment. We concluded a little bracket would be the easiest fix.

The muffler/tips needed to move down away from the valance and to the right towards the gas tank. This bracket did the trick, but may be a bit too low; I might elongate the bolt hole and make it sit a little higher (closer to valance).

Image

But much better...

The exhaust is still not straight, but fixing it would require heating and bending tubes and I got out of there without them charging me anything, so I'm declaring it good enough.
