^WHS^

Uj's do not like to rotate when at an angle and with power to them under permanent 4x4 it will vibrate and not steer properly.

There are 3 ways to convert a series to perm 4x4 properly:

1. Adapt the Series trans box to fit the gearbox (T380, LT77 or auto)
2. Fit a Stage 1 front axle
3. Fit coiler axles

There is a way to convert an LT230 to part time 4x4 with selectable 4x4 using the diff lock lever, but I don't know if the bits can still be bought.

"The reason for fitting FWH to the front of a series is that the old UJ drive joints in a ser ft axle will give "serious" torque steer as they try to self centre under power which is why defenders, disco's etc all used CV joints (even the Stage 1 V8 Ser 3 LWB used CV's)"

Eh...... no its not.

with drive to the rear (normal) there cant be any torque steer
with 4wd selected its like there are no FWH's fitted
and you wouldnt drive in 4wd with the FWH's disconected.

FWH are to stop the front axle internals n prop spinning needlessly when in rear wheel drive.

When read in the context of fitting an LT77 and 230 transfer box it is correct as they are perm fwd..
