Jaseb Posted October 9, 2002 Share Posted October 9, 2002 Couldn't think of what to call this one but my rear wheels stick out by different amounts, I've not really noticed before but the right hand rear sticks out between 5 and 10mm more than the left hand one!? Any ideas? Please don't make it a serious problem as I'm going to Llandow on sunday... Link to comment Share on other sites More sharing options...
SteveP Posted October 9, 2002 Share Posted October 9, 2002 No real idea, but is it possible that the diff isn't exactly central in the chassis? SteveP Link to comment Share on other sites More sharing options...
Jaseb Posted October 9, 2002 Author Share Posted October 9, 2002 Took that to be the problem, was more wondering that it should be central and why wouldn't it be? Edited by - jaseb on 9 Oct 2002 14:57:06 Link to comment Share on other sites More sharing options...
Graham Sewell Posted October 9, 2002 Share Posted October 9, 2002 de-dion or live axle??? With live axle, this may be a strange symptom of the migrating bearing problem where the half shaft starts to move down the axle tube. Otherwise, the position of the axle/de-dion tube is by the A-frame. This in turn is located 'relative to the chassis' using washers and this would have occured at build time.

Jaseb Posted October 9, 2002 Author Share Posted October 9, 2002 Oops forgot to mention it's a de-dion! I had a feeling the A-frame would come into it somewhere Are the bushes in said A-frame easy to change ie DIY job or proper grown up? My biggest worry is that the chassis has been bent at some point ☹️ Edited by - jaseb on 9 Oct 2002 16:34:43 Link to comment Share on other sites More sharing options...
stevefoster Posted October 9, 2002 Share Posted October 9, 2002 De dion bushes last ages and need a press to get them out/in I believe. The live axle ones are an easy job. Could only one of the ears be shimmed? Clutching at straws... /Steve My racing pics, 7 DIY, race prep.

Jaseb Posted October 9, 2002 Author Share Posted October 9, 2002 Hmmm so I need my ears shimmed eh (possibly!) That sounds like the kind of job for a grown up, guess it's going to involve alignment checks and the like, reckon I'll give Chris at the 7 workshop a shout Link to comment Share on other sites More sharing options...
scooby dooby doo Posted October 9, 2002 Share Posted October 9, 2002 meaure if the diff is central in the chassis. the recommendation is for it to be within 2mm. if thats in the middle then it must be dedion, aframe, or the body work...

Peter Carmichael Posted October 9, 2002 Share Posted October 9, 2002 Has somebody replaced a wheel with one with the wrong offset? Have you been measuring the position of the wheels or the hubs? Link to comment Share on other sites More sharing options...
Jaseb Posted October 10, 2002 Author Share Posted October 10, 2002 Thanks PC but I checked the wheel offsets and then measured the hubs to make sure. Link to comment Share on other sites More sharing options...

Morls Posted October 12, 2002 Share Posted October 12, 2002 Is the middle of the 'A' frame centre bush central between the rear lower frame members? If so, is the corresponding bracket on the DD tube central? My 'A' frame needed spacing 4mm (with washers), to the OS to make the 'real' middle (equi distant from each hub), central. Checking and rectifying this is reccomended in Tony Weale's book on the 7 so it's probably not a rare occurance.
