Tony Posted February 21, 2009 Report Share Posted February 21, 2009 This little lady Suffered an OSF impact resulting in repair but not traumatic..... The steering position was initially off-centre but not by much and the rest of the chassis needed some attention but nothing more than you would expect from this type of highly tuned chassis.... To the problem?..... Left lock there is 1 1/4 turns to full lock, right lock there's 2 3/4...... The steering arms have more or less the same number of threads visible. Where has the lock gone?

Rich Posted February 21, 2009 Report Share Posted February 21, 2009 I don't know but will take a guess...was the wrong arm or TRE used even though the same number of threads are showing? Quote Link to comment Share on other sites More sharing options...
Tony Posted February 21, 2009 Author Report Share Posted February 21, 2009 The theads are more or less the same with the steering position straight ahead and the toe correct. Quote Link to comment Share on other sites More sharing options...

CIH Posted February 21, 2009 Report Share Posted February 21, 2009 so the geo is correct ? Quote Link to comment Share on other sites More sharing options...
Rich Posted February 21, 2009 Report Share Posted February 21, 2009 So can we assume that everything has been replaced correctly? Quote Link to comment Share on other sites More sharing options...
Tony Posted February 21, 2009 Author Report Share Posted February 21, 2009 so the geo is correct ? Yep..... Little things to tune, 10' camber nsf, 15' castor osf. I didn't set this since the entire under tray needs removing and the diffuser, since the car wasn't booked i wasn't prepared to remove it. Nevertheless, fundamentally the chassis is true, the steering arms have more or less equal threads visible and the steering is centred, so where's the lock gone?

CIH Posted February 21, 2009 Report Share Posted February 21, 2009 where the TRE balljoints in a distressed position ? Quote Link to comment Share on other sites More sharing options...
Tony Posted February 21, 2009 Author Report Share Posted February 21, 2009 where the TRE balljoints in a distressed position ? Nope, both sides were fine, proved by the TOOT, which was also fine..... To be fair i do know what "may be wrong" with this car but this is a good training tool to keep everyone alert. Quote Link to comment Share on other sites More sharing options...
CIH Posted February 21, 2009 Report Share Posted February 21, 2009 Is it possible the rack may have jumped a couple of teeth (where it meshes with the pinion) ? Not even sure if that's possible, tbh, but I'm struggling too. Quote Link to comment Share on other sites More sharing options...

Not even sure if that's possible, tbh, but I'm struggling too. Your definitely on the right track (no pun intended)..... I have three options that could explain this cars condition, looking outside of the box how many ticks can to mark? 1: 2: 3: Quote Link to comment Share on other sites More sharing options...
CIH Posted February 23, 2009 Report Share Posted February 23, 2009 uh... mechanical fault in the rack (as above) ? powersteering pump fault of somesort ? a failure in the colum ? I'm just guessing now.... Quote Link to comment Share on other sites More sharing options...
Tony Posted February 23, 2009 Author Report Share Posted February 23, 2009 1: Mechanical fault in rack 2: Racks position not horizontal 3: Racks position moved transversely Quote Link to comment Share on other sites More sharing options...
CIH Posted February 23, 2009 Report Share Posted February 23, 2009 No2 would show as inconsistant toe tendancey...? Quote Link to comment Share on other sites More sharing options...
Tony Posted February 23, 2009 Author Report Share Posted February 23, 2009 No2 would show as inconsistant toe tendancey...? Yes if the steering arm and wishbone radius was out of sync but i never tested for tendency...... It also had an offline steering wheel due to a new steering arm being fitted, so there was other areas masking the complaint. Quote Link to comment Share on other sites More sharing options...
