spit1500 Posted July 24, 2007 Share Posted July 24, 2007 had this 1360 for years......since 1991......but its been of the road for a few years so ive decided to get her mot ready, jacked the rear end up and the drivers side drum sits well clear of the back plate, maybe an inch or so. ive never really done anything to the rear end as ive never needed to, is this common or a odd case, any ideas of its cause, its almost as if the shaft is too long.....maybe some one has fitted in incorrect uj over its life? are they different in any way? please help ....im concerned its something major.... :'( :'( Link to comment Share on other sites More sharing options...
Deleted User Posted July 24, 2007 Share Posted July 24, 2007 Have a look at the bearing carrier, you'll prob find the bearings are shagged and the shaft has slipped through the carrier Link to comment Share on other sites More sharing options...
CharlieB Posted July 24, 2007 Share Posted July 24, 2007 Looks like someones fitted a late Spitfire driveshaft, they're an inch longer!Has it been driven like that?Edit: Doug's idea seems more likely! Link to comment Share on other sites More sharing options...

Deleted User Posted July 24, 2007 Share Posted July 24, 2007 The hub is attached to the drive shaft by way of a woodruff key and the nut on the end of shaft ..so will not be affected by any bearing failureTake a look from the other side to the last pic, where the drive shaft goes into the bearing housing Link to comment Share on other sites More sharing options...

Deleted User Posted July 24, 2007 Share Posted July 24, 2007 The backplate bolts onto the bearing housing ..the bearing housing is connected to the vertical link with a bolt through the trunnion..the head of that bolt is visable in pic 3 just up and right of where the shock attatches to the vertical link...so even if bearings are completely shagged the backplate will still not rotate Link to comment Share on other sites More sharing options...
spit1500 Posted July 24, 2007 Author Share Posted July 24, 2007 i meant that it rotates on the axis of the top bolt....ie the bottom goes inwards ....not rotate as the wheel does......oh...im confusing myself....LOLin anycase ill try and strip it tomorrow and report back.....if the rain holds off.... :-/ :-/ Link to comment Share on other sites More sharing options...
Deleted User Posted July 24, 2007 Share Posted July 24, 2007 Sorry i get what you mean now ..i think..the back plate and bearing carrier/vertical link does pivot on the trunnion and the spring bolt but it shouldn't move along the shaft normally it just alters the camber of the wheel,but with the bearings worn or failed you will be able to move the whole assembly to and fro on the shaft a bit ...only saying this as that is exactly what my herald did ...looked exactly the same Link to comment Share on other sites More sharing options...

willows40 Posted July 25, 2007 Share Posted July 25, 2007 this has happened to me its the wheel bearing shot. Link to comment Share on other sites More sharing options...
Richard B Posted July 25, 2007 Share Posted July 25, 2007 it's F*&^$ed;best order a bearing set, half-shaft and a U/J from Canley, Paddocks, Rarebits etcps you might want to do the bearings on the other side in the near future. Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 26, 2007 Share Posted July 26, 2007 we had a shaft on our vit which had no shoulder for the bearing position on the shaft, it only relied on the bearing fit to postion it relative to the back plate , if it moved then it would have looked just like yours,, did this happen after you let the jack down ?? peter Link to comment Share on other sites More sharing options...

heraldcoupe Posted July 26, 2007 Share Posted July 26, 2007 The inner bearing runs directly on the shaft, the shaft itself is now scrap. Fitting a bearing alone will NOT fix this. By the time things get this bad there is a good chance that your trunnion housing is also destroyed,Cheers,Bill. Link to comment Share on other sites More sharing options...
C Mallock Posted July 26, 2007 Share Posted July 26, 2007 Although identical its best to run half shafts in the same rotation that they have always run in.I have a pair of shafts/bearing housings/backplates in my garage but the bearings and UJ's are shot.I removed them from my Herald when i swopped them for some units i reconditioned. Sadly the side which shot its bearing is the same side you need the bearing was destroyed due to the backplate bolts coming loose and letting water in and greese out. If you want to take your chances on the shaft being usable you are welcome to them.You will need a puller to remove the flange from the shaft but its straight forward Link to comment Share on other sites More sharing options...
