SPendrey Posted February 5, 2015 Share Posted February 5, 2015 I've been reading all sort of suggestions for causes of 'transmission vibration' from handbrake adjusters falling off to diff failures etc. My symptoms were these... When reversing I would feel resistance coming on and off, like the handbrake was binding, Sometimes a little, sometime a full "clunk" as if a gear tooth or something had been skipped. When driving forward all was fine, but if I shift to neutral then there was very noticeable vibration, couldn't pin where it was exactly, but enough to cause steering wobble. So, I figured I'd start by removing one prop to identify if the fault was forward or rear of the TX box. In my mind, the handbrake was the culprit, I was expecting to see a return spring broken or something like that... so I removed the rear prop first, and then took a short drive just to see if anything changed. The symptoms were there, just less so. Next step then was to remove the handbrake drum and see what fell out. I followed one of Les's threads and was expecting the screw that holds the drum to be a pig. It could be undone by finger! Then I expected the flange nut to be tight as anything, the socket driver's weight alone made it move!! That's not right. After cleaning up a little (no real gunk in there, but as I was in I cleaned) I tightened it all back up and the vibration is gone! Glad this wasn't a big issue in the end, if only all the problems I have were so simply resolved! Quote Link to comment Share on other sites More sharing options...

SPendrey Posted February 24, 2015 Author Share Posted February 24, 2015 Hmm, the vibration is back, and I've no doubt it'll be that nut again. So, I'll replace the nyloc nut to ensure a good 'grip', but my question to all is whether there's any issue with using threadlock too? I know the nut shouldn't come undone, but wouldn't threadlock be a belt and braces approach? Thanks, Scott Quote Link to comment Share on other sites More sharing options...
bear Posted February 24, 2015 Share Posted February 24, 2015 Are you happy that your rear donught is ok. Read quite a few threads of people with similar probs to yours and it turning out to br that. Griff Quote Link to comment Share on other sites More sharing options...
SPendrey Posted February 24, 2015 Author Share Posted February 24, 2015 Well yes, I took it off to remove the rear prop, and it is a GKN one and appears to be in good shape. And, with that nut clearly loose, once tightened all was good for a while. What I'm thinking it that the nyloc part of that nut is knackered.
