Third gear clonk

Hi All

My 110 defender as a bit of a clonk when changing up it only seems to do it between 2nd and 3rd and coming down is ok i have tried slowly let out the clutch is helps a bit, it feels like it is coming from behind me when driving.

any ideas ?

Thanks

Hi sorry its a TD5

Cul'd be A frame balljoint

Thanks will check it out, is it a big job ?

Naah bolt on job, especialy if you buy it with it's base complete, but try see if it's got any play in it first though.

also remove rear axle drive flange caps and check wear in splines of drive flange and shaft

did one last week, will put some pics up tomorrow of the splines, forgot to take pictures.

I will check for play first, photos would be great many thanks

Hi there seems to be no play in the joint i can not move any think under there all seems solid

Well next moove i'll gues is to try the UJ's , and/or even take the PTO cover to look at the g box main shaft splines, ps while at the A frame did you check for any moovement on the bush end.

Granted, it might seem tight when your prodding it by hand but once you have a 1750kg Landy exerting force on the components it can soon start to clonk. Sometimes a pry-bar is a good idea to see what will move excessively under force.

Park it on the flat, lie under it and have a mate roll it back and forward a bit while you watch all the bushes and joints. I have the same problem, if I roll the Landy back and forward I can hear it clonking away. I will work out exactly what it is soon, I suspect the A-frame bushes or ball joint.
