Front driveshaft/4wd query

[twotanks]

Hi everyone

Can anyone confirm if the front drive shafts should be turning when in normal two wheel drive?


Thanks

In 2wd the front drive shafts should not have motion going to them from the engine and gear box. If the auto hubs are working correctly they should not be getting any direct drive from road wheels however I wouldn't be surprised if there was a little drag in the hubs causing the shafts to turn. It is possible for the auto hubs to stick and be perminantly engaged causing the front transmission as a whole to turn with the road wheels.
Also once you have been in 4wd you should run the car in the opposite direction in 2wd for a short distance to release the hubs.

Thanks Jim - about six months ago I took out the workings from the two front auto hubs to see if diesel economy would improve and also with the idea of maybe changing to AVM manuals. Its my daughters car and she was always too busy to let me get to work on it. Of course with the recent snow she went to select 4wd and wasn't impressed that it wasn't working. I cleaned up the auto hubs and put them back but I can't be sure if the front wheels are powered. In normal 2wd the front drive shafts are turning. If I put it into 4wd L everything seems very slow but still can't tell if the front wheels have drive.

Find some clear dryish tarmac, select 4WD and drive in a tight circle, forward or back - if it all 'tightens up' and starts skipping a bit then you know you are in 4WD. :thumbs

It is difficult to know for sure isn't it. After I had changed my brake rings first time around I got stuck in some nice Derbyshire mud and got all 4 wheels spinning :lol:lol just to prove it of course:lol All I can say is manuals were the right choice for me. Mine have been locked since before Christmas and will remain locked until the cold spell ends. At the end of the day you have to choose what's best for you.
One word of warning about the auto's, now you've put them together again if you hear a clicking noise as you drive along in 2wd then it's possible that the hubs are stuck as mine were and one of mine badly over heated.

If I put on manuals and she forgets to manually turn them back to free wheeling after the ice is there any likelihood of any damage being caused?

Hi No damage should occur but fuel economy may suffer

as just said nope, but also if she needs 4wd again she dont have to get out again either...

Thanks Guys - manuals it is.

the last t2s had fixed hubs, frankly free wheelers goes back to
landies trying to up mpg. vehicles with aero dynamics of a brick
tend no to really benefit.

oh and my troll has autos which can be levered into manually
locked for good measure, best of both worlds??
