I doubt very much the steering lock can seize whilst driving- that would be a truly major issue, for sure I have never read of it happening.

The base problem here is the rack- no doubt about it- just a question of whether the problem can resolve itself- mine did not- a new rack fixed the issue.

I once set off on my motorcycle with the the steering lock engaged- now that was fun- just ask ask my friends shrubbery!

Regards

Does that bring back memories! When I was a motorcycle dealer I saw this happen more than once...

Good to know I am not the only "dumb ***" on the planet!

do you know of anyone getting a locked wheel while driving?
Personally? No. However my Indy shop has talked about it, though I didn't ask them if they had seen instances of it. They flagged mine since the key is very loose in the ignition barrel and it needs replacing along with the ignition wiring harness. Just waiting for or friends in Germany to finish cutting the lock.

If you are indeed having ignition lock problems, you would probably see many other issues, like I have. Warning lights pop up, headlights don't work ...then you jiggle the key and all is fine.

Seafoam makes a "trans tune" and since our PS racks use ATF I tried that on one of my cars. It has power assist only to the right and, unfortunately, it still does not have assist to the left. Still, it was easy to try.

Interesting how a few of us have highlighted problems on left lock but no one[?] has reported any history of problems on right lock.

Perhaps this suggests a vulnerability in the design of the rack somehow- a chamber or passage that facilitates a blockage of some kind?

Sorry for not chiming in on this earlier, Ed. Just logged in to see your PM.

I did have a similar issue last year... https://rennlist.com/forums/928-foru...y-ideas-2.html

Mine happened while doing a u-turn.

Besides unlocking the steering and working it to full lock. When I got home I lubricated the heck out of the universal joint with some PB Blaster and worked the steering back and forth (full lock to full lock) and I've had nothing come back.

There is nothing scientific about what I did but it seemed as though the UJOINT (item 8A in the below) was binding and I figured a little lubricant wouldn't hurt

FWIW, my rack was replaced 13 months ago.

And here I am, reporting back...

Got my car back today and it did, in fact, need a replacement rack. Probably the spool valve. A few weeks ago, I replaced the filter (reservoir/filter) and did the fluid replacement / flush to no avail, gave up and took it to the shop a couple of days ago.

The big, somewhat unexpected bonus, though, was that I now have a fully functional high pressure PS system with more assist / lighter touch. I'm happy. Oh, and a big "Thanks!" to Karl at Rennsport KC for great service on this latest episode.

Interesting....
I've had something similar happen on my '82 but only on very hard sharp right hand turns...
Usually followed by a little overseer and some suspicious blue tire smoke!! ;-)
Anyway it was for only a split second while under full load and while straightening out the wheel..
Very disconcerting for sure.. I think we diagnosed it to be the steering U-joint somehow binding on the exhaust manifold on hard right turns.. Will confirm while the old engine is out and before the new one goes in..
