landybear Posted February 14, 2008 Share Posted February 14, 2008 Hi all, further to my post about month ago, vibrations seem to be getting worse. When in say 2nd at 20 MPH or when something is under pressure like 50 - 55mph up a hill on dual carriageway. I don't know if its gearbox which was new only 3 years ago and or original transfer box (1987)- maybe bearing (dunno know anything about this though) i have checked play in UJ's the best i can doesnt seem to move pulling and pushing resolves in no movement maybe i could go more brutal. If i put my head down it seems to be coming from gearboxes area and then moves back a bit behind bulkhead area. I drove down to PLymouth yesterday 60-65 was fine but i could be going too fast to increase frequency of vibration??? Not sure Any help appreciated.

Yostumpy Posted February 14, 2008 Share Posted February 14, 2008 have you checked the UJ'S, I know you said they're fine, but there are two sizes fitted and if someone has fitted a smaller one when a larger one should be, (as i did on my spitfire) then I moves around and thus throws it off balace.

landybear Posted February 15, 2008 Author Share Posted February 15, 2008 No i think the size is fine. Just cant work it out. Might not be being brutul enough when checking. What is 'play' defined as?? Quote Link to comment Share on other sites More sharing options...
Simon Smith Posted February 15, 2008 Share Posted February 15, 2008 I have had UJs that feel fine on the car, but were completely knkrd when the prop was taken off. I now treat UJs as disposable items, any noise or vibration I just change them. Quote Link to comment Share on other sites More sharing options...

I was going through lots of front prop UJ's until some kind person on ere explained about offsetting the UJ's by .. i think it was about 30degrees. It also made things alot smoother. This is done by taking the prop off and pulling the prop apart on the splines and slotting it back together at the right angle. Quote Link to comment Share on other sites More sharing options...

This applies to the front prop only though. Quote Link to comment Share on other sites More sharing options...

Take the front prop off first and check its flange angles. Give it all a good feel. I do like feeling flanges Quote Link to comment Share on other sites More sharing options...
V8 Freak Posted February 16, 2008 Share Posted February 16, 2008 While front prop is off, engage central difflock and go for a drive. If vibration still there it's not front prop/front axle. Replace front prop, remove rear and drive again. If still there, it's likely to be gearbox / transfer box related. (I'm assuming you have checked wheel balance etc. already!)
