1piece tailshaft problems

[Mick]

I recently installed a nine inch and a one piece tailshaft into my vh. been having troubles with the tailshaft rubbing on the floor when going over bumps. its lowered about 2.5 inches all round. I also have an adjustable panhard rod. anybody had similar problems and know of a solution.

Simple answer - the tailshaft is unsuitable.

You must do some mods such as increase the height of the vehicle AND install HIGHER bump stops or go back to a two piece shaft.

If you chose to stay with the one piece shaft, you will have to have it balanced again and checked for damage since it has hit something once upon a time.

If you dont, think of what could happen. You're doing 60km/h or faster and hit a big bump, tailshaft hits the floorpan and buckles it, it rips apart at the gearbox, hits the tarmac of the road, digs in, flips the car straight into oncoming traffic or a tree or something.

Dont think it wont happen. It is a serious defect that most likely wont be picked by highway corrupt revenue raisers. Have it fixed immediately for your own safety and peace of mind.

Once a tailshaft gets hit by somethings its rooted....

Maybe try raising the floor....a big hammer comes to mind.
A tailshaft loop sounds like a good idea too

Or lower the height of the gearbox if you can- add some spacers to the lower gearbox mounts.

If there is too much adjustrment required - Karl is on the mark with a Big Hammer.

My friend's escort required a whole new tranny tunnel (after the tailshaft tried to wedge itself up his ass!)

I'ts only a few days work to those in the know..

mad - by lowering the gearbox introduces angle errors for the unijoints on the tailshaft which will lead to excessive wear and tear on all driveline components in the diff, unijoints, gearbox etc. Only a few degree's is all it takes to stuff it up. A CV joint is required if there are angle errors between the diff and gearbox.

i say go the sledge hammer.

Damn tailshaft place which made it up should've known whether the VB-VL floorpan can take a one piece tailshaft!
