Hi Guys
Just wondering on a few points of interest.
I looked at my steering bits today while my son turned the steering wheel.
It looked to me that all the parts move as they should.
But how do I know im right, what should I be looking for when the steering
is moving. ?????
I have a noise in the front of the cruiser and im not going to bore you lot
with the details cause I really dont have any.
I hear you say thank god for that.
I took the front wheel off and turned the hub while it was in neutral.
I found something I was not looking for at all.
When I turned the hub there was a slight delay in the pick up to the drive
shaft and then a sound like ching then the shaft was engaged.
Is this normal or is something worn or starting to ware out.?????
When under the cruiser if I grab the drive shaft coming from the engine to
the centre diff with my hands around it and try to turn it, it will turn
about 1 to 11/2 cm before it seems engaged. Is this a normal amount of play.
?????
cheers

John,
What you've discovered is a slack in the drive train. That is to be
expected in a car that 's 14 years old. You can normally hear a clunk
when you change from front to reverse. It's not quite healthy, of
course, but not alarming.

Your Hayes manual will help you diagnose.
I had similar noise.
It eventually turned into a loud "clank" - as opposed to the soft "clunk" when changing from forward to reverse
Just got it fixed last last week - and am back to the soft "clunk" :->
Have the part name at home - will forward it tomorrow FYI

Hey Roman
Ok so whats the cure or the bits needed or what can be done to my poor drive
train to improve this slip.
If left alone does it usually get worse or reach a point of slip and then
stop after that point.
Just interested , not that I want more expense, but if it could be solved
now and save a bigger bill later all the better.
cheers

John,
There are different reasons for a drivetrain clunk in the front axle
and rear axle. Ask your mechanic. Even a Yaris guy will tell you if
it's exceesive.
If it isn't, it's pretty expensive to eliminate and the advantage is
very hard to appreciate.
If it is, you'll hear more and more noises while going forward and
back, accelerating or changng gears. Every clunk is one piece of metal
hitting another, so the weaker piece will have to give at the end.

John,
"When I turned the hub there was a slight delay in the pick up to the drive
shaft and then a sound like ching then the shaft was engaged."
Between the propshaft and the wheels you have 5 places where you may have
excess slack:-
The propshaft universal joints - there shouldn't be any play here at all.
The propshaft splines - there shouldn't be any play between the two halves
of the prop.
The ring and pinion inside the diff - there will be a small amount of play
here if set up correctly.
The differential side gears - play here should be negligible, but you won't
be able to tell it from ring and pinion play without dismantling your diff.
The CV joints - shouldn't be any play here, and they'll clonk repeatedly
when making tight turns if they are worn - I'm sure you'd have noticed this.
The CV to driveplate splines - probably your most likely place for excessive
wear as they sometimes aren't sufficiently greased and are subject to
frequent movement. They can be accessed behind the small domed steel cap on
the centre of your hub - if they are totally devoid of any grease they might
well be wearing prematurely.
If you're testing for play by lifting one wheel up with the other on the
floor and the car in gear do bear in mind that you are getting all the
accumulated play of both sides of the axle, the prop, the transfer case and
the gearbox - this will probably be enough to worry you even if everything
is ok.

Hi John,
The cure is to go for a drive in a similar vintage range rover and then
when you get back into your truck it will feel like it is brand new
compared to the drivetrain slop and transfer case whine of the rover.
Cheers,
Craig.
