Remove the the universal assy from the hollow center column tube.
Loosen the two allen set screws that are in the large OD billet spacer. (the lower bearing is right behind it).
Slide the spacer and bearing out.
You can now pull the steering wheel and center tube out and access the upper bearing. (Outer support tube is not disturbed)
I take it that I don't have to do anything with the blinker arm assembly? Just leave it secured to the outer support tube?

Correct, the blinker is attached to the outer tube and is not disturbed either.

Also that bind really can't be felt with the wheels installed as the caster pulls the wheels left or right while jacked. A binding steering spooks me.
The BDR uses a flipped RHD MR2 rack.

You probably should just replace the the steering shaft and joints with beefed up parts.
Shopping list is here. You most likely will not need the center Heim bearing I added to mine.
Steering shafts upgrade

Further details are in this thread.
Can't take any credit but you should consider Speedbrakes steering upgrade.
"While I was at it I replaced the upper and lower steering shaft bearings. PN 32-31-1-158-835"

FYI. These bearings did not fit my steering outer support tube nor the inner steering tube. Both the OD and the ID of the bearing was too big. Eyeballing it I would say the bearing diameter was probably about 1/8" too big. Again, this is on a 2011 build with all stock components from BDR.

Yes, the PN 32-31-1-158-835 are the BMW bearings.

No, on the knowledge of will-fit replacements.

However it would be great if you would disassemble yours and mic out the measurements and then determine which bearings fit or are close to a drop-in replacement.

Default Lower U-joint

Give Woodward a call or email them and they will make it for you. That's what I did back in 2019. Here is what I sent them along with their response


Hi.

I have a Backdraft Cobra and I am doing a steering upgrade. Another owner did the same upgrade and he said I need a Ujoint PN UA116109 3/4" Double-D and 14mm-34 spline. He said he got it from you. Is it available? I see a UA116110 but no 109 on your page. Thanks


Here is the email I received from them.

From: Alyssa N <sales.woodwardsteering@gmail.com>
We can combine any two ends we manufacture to make a u-joint, so yes, that is a u-joint we can supply. Please provide shipping address, phone number and payment information.

Great, I called them this morning. Hopefully they get back to me. So that top shaft fits in the hallow steering wheel shaft. I know once I get all the parts I can figure it out �� or bug you guys to death. Did you notice a good improvement? With this project and the front fan project I’ll stay busy out here for awhile. SPM

Default Improvement

It is quite noticeable. No more flexing or twisting along the steering column. I strongly suggest installing Camber Plates. They are another significant improvement. The stock top shock mount is encases in rubber. With Camber Plates it's steel. Makes the handling more precise. The final improvement would be to bag the original manual rack.......It's garbage.

Is there a kit I can buy for the rack. What would you recommend? Is it something I can do in my garage? Itís kind of fun working on this thing. Itís getting addicting. I found myself living in my garage haha Anything I can do to make this car better Iíll do. I want to add those fans in front. Iím very happy with the 15 inch rims and a Billboards. Being in Ohio Iíll have all winter to improve it. SPM

Default Rack

No. there is no complete kit offered that I know of. The prevailing thought and the rack that seems to be the most popular to convert to would be the rack from a BMW Z3. This rack will be 2.5 turns from lock to lock which is quite an improvement over the 3.6 stock manual rack. You will also have to provide a pump, rack mounts and different tie rod ends. Their are a few Backdraft dealers/shops like Vintage in Connecticut or Miller Speed in California who do the conversions.

If your booster is failed there are threads on the site detailing the replacement parts.

I'd start by making sure you actually have a check valve at the booster, VS a a plain 90deg plastic elbow. (like mine had)
https://shop.advanceautoparts.com/p/...ck-valve-80190
If you have a non-check valve elbow you lose all your built up vac boost each time you go back to idle.

Mine still works so-so as I only have 11in of vac (still better than the solid roller I removed which had 9in.) But the brakes are adequate and will lock up if need be.

The bearings are sold in pairs.
