Ed Posted November 13, 2004 Share #1 Posted November 13, 2004 On the steering rack there is a U-bolt clamped to a bumper looking thingy. Does anyone know what the purpose of this is. What does it do? Link to comment Share on other sites More sharing options...
Bambikiller240 Posted November 13, 2004 Share #2 Posted November 13, 2004 It is a factory add-on to stop excess flex of the steering rack. When the rack flexs, the flex is limited when the "bumper thingy" contacts the cross member. I know it has been sicussed before on this site, but a quick search didn't turn up the thread.

Ed Posted November 13, 2004 Author Share #3 Posted November 13, 2004 I tried doing a search and after the second page I gave up. Does the bumper go in the center of the rack or on the side? Link to comment Share on other sites More sharing options...

Ed Posted November 13, 2004 Author Share #6 Posted November 13, 2004 That's the one. I've noticed that they are all positioned at an end, close to a mount. Can it really stop excess flex from there? Or does it prevent rotational torsion? Link to comment Share on other sites More sharing options...

hls30.com Posted November 13, 2004 Share #8 Posted November 13, 2004 Thanks Carl and Ed, My rack does not have such a doohickey on it-wonder if I should hunt one down? Course, who's to say my rack wasn't replaced at some point in the last 30 years or so-I will have to get buisy with the club cd, and see if any differences can be noticed between the early ('70-'73) and late '74-'78) racks.Will Link to comment Share on other sites More sharing options...
Ed Posted November 14, 2004 Author Share #9 Posted November 14, 2004 http://www.classiczcars.com/forums/showthread.php?t=8438&highlight=steering+rack+limitThanks for the link Carl. Unfortunately it still doesn't really answer what it's for. Everyone just guessed and gave assumptions.Ohh well,..... Link to comment Share on other sites More sharing options...
sblake01 Posted November 14, 2004 Share #10 Posted November 14, 2004 Thanks for the link Carl. Unfortunately it still doesn't really answer what it's for. Everyone just guessed and gave assumptions.Ohh well,.....In post #2, it seems to me that Carl answered the question. I asked my Z mechanic Elvan about it and he says the same thing.

Bambikiller240 Posted November 14, 2004 Share #11 Posted November 14, 2004 Actually, I wasn't "guessing". Sorry if I cannot prove the answer as I do not remember (nor do I care to re-read them all for this purpose) which of the many manuals I have read that it was in.Now don't take this wrong, but IMO what should really matter is that it WAS installed by Nissan for a reason, not by some schlub who purchased it from Grand Auto. There's one way to 100% confirm the reason it's there. Leave it off and see how the steering rack fails. Link to comment Share on other sites More sharing options...
hls30.com Posted November 14, 2004 Share #12 Posted November 14, 2004 Carl, I am realy in a quandry about the rack on my '72, no hints(scratches, marred or worn paint-even on the crossmember) that there ever was such a doo hickey installed!The question becomes: Do I replace the rack to get one?
