My 1988 Defender 90 has started making a knocking/rattling sound (sort
of a loud tick tick tick) when making hard turns (sounds like it is
coming from the front right hand side), this is before it gets to full
lock, and when on full lock the pump belt wines.

I have replaced the pump and pump belt and however tight I make it, it
still wines. I think this must be a steering box problem, as all else
seems ok, I have checked oil levels, greased all that can be, replace
track rod end ball joint etc. etc.

I have a steering box seal kit, but before I attempt to fit it I would
be grateful of any advice if this is what may be causing the rattling,
do you think the seal kit will help, and any advice on how to fit the
kit.

Cheers in advance.

first thought is a knackered CV joint.

Steering pump always will whine in full lock but should not tick.

I would also doubt the steering box would make a tick tick noise as
all is stationary in there once the wheel is "pointing the right way".

That sounds like a CV joint is past it's best from your description.

Without hearing it its difficult to be certain, but the pump should
make a whining noise on full lock, a sort of buzz/screech is the
best description I can come up with!

Gerenaly speaking, the steering boxes only work or not, with or
without leaks (unless the someone has wound up the adjustment
so much that the poor thing can't turn freely) - I can't see
that there is anything in there that can screech or tick.

FWIW, I've always thought it was bad practice to hold the steering against
the lock stops. The pump stops whining or whines much less if you back off
the wheel a fraction.

This is generally a *bad thing to do* don't hold 'em on full lock for longer
than absolutely necessary.

OK, CV joint seem to be general consensus, thanks very much, now to
show my real ignorance, I have no problem in identifying CV joints on
lesser vehicles, but where is it on my baby (that's the 90)??

Andy

 
ohhh i see, now that makes sense.

just been and had another look at it, with another fellow landy owner,
and it looks as though it may actually be the steering pump, it keeps
locking up (excessive squealing) and the rattle could be coming from
their also (or problem is in opposite wheel to what I thought)?? so now
i have another possibility (wouldn't be so bad but i only replaced
the pump about 6 months ago).... perhaps i should stop driver in mud
and deep water....... but then again........ eeee I love owning a Landy
:)

 
Steering pumps are not consumables. If its gone again did you bleed
the air from it correctly the last time it was replaced? Have you any
ATF fluid in it?

Try jacking one wheel up off the ground at once with wheel in full
lock, engine turned off and turn the wheel about the axle (not
steering lock). You may need to do this at both sides to identify
which joint is duff. A "fubarred" CV joint will sound itself, if its
the steering box or pump it will not.

i had a cv joint go on me some years ago , it does make the noise you
mention, if i were you id fill the swivel housing with oil or fluid
grease pretty darned shaprish before the joint goes bang on a tight
turn .

the other thing it might be is the tyre tread rubbing the chassis or a
mudflap , this usually happens with larger diameter tyres, ie 7.50x16
mud tread or 31.5to 33x15
..

if it is a couple of knocks from under the floor on tight turns it
might be the bolts loose in brackets for radius arm bushes , on the
front axle , brackets on drivers side .

check wheel bearing play as well .

 
i have tonight checked both swivel housings, and both at correct level,
its one shot grease. the drivers side radius has very slight play in
it, and may require new bushes, (will be ordering them) as far as i can
see the previous owner seems to have replaced all bushes down the
passenger side, but not the drivers side, it wouldn't be the first
that i have had to replace in the last 10 months. i have checked all
other fixings and they seem OK.

the large wheel point is a good one, i have BF goodridge 7.5 x 16 on
27inch wheels.

i also jacked up the front and checked wheels, seems to be no play, and
only sound when turning them was from disks rubbing pads.

this is getting annoying now, and i think i am getting more paranoid.

My husband and I hear a knocking sound also but we've been told by two
different shops that we need to replace the small block. One mechanic said
that it looks like it was driven without oil and the engine locked up. Then
the dealership or someone else forceable unlocked it and sold it (to us).
We already put $3k into repairs and car rental expenses and it's still going
to take another $3k to replace the small block with a used one. Yuck!! My
husband doesn't want to get rid of it though. I don't blame him. It's a
solid vehicle.
