toyota surf

Gawd dat tells evry1 evryting.

Reading between the lines it's a later smurf wit the diff dat locks and dee diff is knacked.
it ain't an early 1 wit either manual or auto hubs.

The two back wheels and the steering wheel. Was that not obvious!

muzz67, Apr 21, 7:49pm
meybe op means 3wd is only one front hub engaged (not both)! sounds like simply diff wind-up buggering up steering!

x2 try it on gravel.

virgo77, Apr 22, 5:06pm
auto hubs have been changed to manual hubs hence 3wd and only gets used offroad just so you know

virgo77, Apr 22, 5:09pm
and is a 1991 2.4t with ifs

Still makes no sense. Are you only locking one of the front hubs!

gadgit3, Apr 22, 5:24pm
Any body been under the bonnet playing with vac lines!

bwg11, Apr 22, 5:36pm
Why do you lock only one hub! One front hub locked is effectively 2WD, because of the differential, unless you have a limited slip or locker on the front.

virgo77, Apr 22, 6:00pm
locking 1 wheel because it wont turn corners if both are locked, vac lines unchanged

a.woodrow, Apr 22, 6:05pm
Fault in the front diff causing it to bind.

bwg11, Apr 22, 6:08pm
Something very wrong here - I'm beaten.

gadgit3, Apr 22, 6:12pm
Dose it favour one side! ie free wheel L/hand lock R/hand no issue but opposite causes the issue also! if so could be a CV joint issue

farmboy11, Apr 22, 6:15pm
Broken C.V joint

a.woodrow, Apr 22, 6:15pm
Very unlikely to stop the steering wheel from turning

virgo77, Apr 22, 6:17pm
both cv joints are fine

gadgit3, Apr 22, 6:21pm
Then if the CV's are fine and no one has moved the vac lines on the powersteering pump. moving into 4wd with hubs locked shouldn't restrict the steering wheel to half a turn.

gadgit3, Apr 22, 6:22pm
You'd be surprised

virgo77, Apr 22, 6:24pm
if i jack it up off the ground it will turn fine in 4wd

tnt423, Apr 22, 6:28pm
Can you force it to turn more!

virgo77, Apr 22, 6:29pm
if i get angry with it

r15, Apr 22, 6:30pm
so what happens when you try turning!
eg steering wheel wont rotate
or
vehicle will move forward but feel tight and skid in the process
