Craigb 2 Posted March 12, 2007 What are the symptoms of a bent rear stub axle , and how do you measure it . My car has a strange quirk , that i think may be down to the stub axle. On left hand bends its quite neutral , good turn in due to the added caster etc . But on right handers it has additional turn in , it not vicious or any thing , and is very predictable . so probably not bush related . Just something that i would like not to have to think about mid section . Any ideas anyone Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted March 12, 2007 Is the additional turn in caused by an ovalled balljoint hub hole? Sounds like one of mine did when I had this or a spit rear beam rubber mount which I put down to a bent stub axle but I'd guess you have solid ones fitted which will count that out of the equation. Not sure how to check without removing the suspected one & comparing it to a straight one although would the wheel bearing show if its bent? (tighter than normal) Graham.

I'm using the adjustable PTS wishbones up front , so the ovality of the hub is taken out of the equation as is the rear mounts which are solid as you surmised. it definaly feels rear related though Share this post Link to post Share on other sites
Rob Thomson 6 Posted March 12, 2007 Can't you just stick it on a 4-wheel chassis alignment thingy? Surely that would show any mis-alignment of the rear wheels. Share this post Link to post Share on other sites
taylorspug 7 Posted March 12, 2007 Either as Rob says, or string the car up using 4 axle stands and some fishing line and measure the toe readings on all 4 wheels from this. Share this post Link to post Share on other sites
Craigb 2 Posted March 13, 2007 Its getting tracked up Saturday morning , so we'll see what the alignment people make of it Share this post Link to post Share on other sites
Craigb 2 Posted April 3, 2007 Having started this thread with the statement that i didn't think it was bush related, how wrong can you be? I had the car 4 wheel aligned , which showed nothing untoward . so i started the pre event spanner check , at which point i noticed that on a previous event i had replaced a std wishbone bush with a poly bush . Because i didn't have a std one lying around at the time . As this was the only none std part on otherwise a known good front end , i replaced it and hey presto , all the unwanted oversteer disappears . as far as i'm concerned . i will never fit a poly one again . They be the work of the devil do they !! Share this post Link to post Share on other sites
