Very cool work, yall! A nice reading thread. Sorry that I'm the dummy who makes the random comments! I have not had a manual steering car in a long time. It is common for the manual steering cars to have a larger steering wheel. I wonder if you have room, or tilt column, if a slightly larger diameter wheel could pay dividends.
It's interesting how the splines for the manual rack are coarser than the power rack splines
Along the same lines, I bet the splines are beefier because there is more actual force being applied on a regular basis.
The car is noticeably quicker to accelerate! I did some searching, and apparently the PS pump consumes approximate 4-1/2 hp driving in a straight line, and 6 hp going around turns, as measured by these guys. That's a significant percentage for a 90 hp engine.
That is very interesting!
I could not find any examples of a manual rack swap on a B4. Maybe this is the first one?
Good job being a Trail Blazer!

Great point, I know the Vanagon used a 40 cm steering wheel on the PS models, and a 45 cm diameter on the manual steering models. I'm not sure if Passat was also sold with different diameter wheels. Time to do some research...

Too add some more information, because we can never have enough of that, right?

Found a VWVortex Post about replacing a manual rack on a Corrado and it has some good pictures about setting up the tie rods. Honestly much easier to follow than the procedure I found earlier

I'm wondering if the manual rack can be removed without dropping the subframe on the Passats too since it's a fair bit shorter than the power one 🤔

One last update from me, just got the manual rack in mine and everything went together perfectly. The only thing I have to add, as this post is already plenty comprehensive, is I found an alternative solution to finding the boot

I simply got the b4 steering boot and trimmed it like this


And took the mk2 golf manual rack boot and trimmed the firewall end off


And I simply super-glued them together. Super glue is very good at bonding rubber if the surfaces are clean enough. I added a layer of silicone just for a little extra moisture protection


And it fits perfectly! I was pleasantly surprised with how well it works

Also, the EAA engineering kit is very nice and includes almost everything you need as far as mounting hardware and it even has a boot for a mk2 golf w/manual steering. It did take a while for me to actually get it as they were going through some changes but I eventually heard back from them and everything showed up okay

Anyways thanks @tdi_in_va for gathering all the information I needed! Everything fit perfectly

That's awesome, nice work there @HardToHandle

On a somewhat related note, I've started gathering parts for converting the driver's door to a manual window. I'll keep the power one until the regulator teeth wear off (again), and then do the manual swap. I may ping you if I have questions!

These racks last a really long time with regular fluid replacements. My original rack has nearly half a million miles on it and doesn’t leak a drop.

I agree, however I changed the fluid regularly in mine with Pentosin hydraulic fluid

But I can't control how the previous owners took care if it
