re the water pump job. With the engine in the van, you don't( and
can't ) remove the crankshaft pulley.
Replacing the w. pump with the
engine in the van, it's an awkward fiddly job, but doable.
one way I identify bad wheel bearings is by swerving gently on smooth
pavement, at about 35 mph ( 60 kph ) and listen for the rumbly sound to
change.
Say it's noisier going straight, and swerving left, but quieter
swerving to the right, you conclude that it is likely a right side wheel
bearing, as the load on it is reduced when swerving right.
on syncro's , with noises and vibrations, I have gone just nutty trying to
track down the bad parts, which were not very identifiable without
disassembly.
On one, that vibrated significantly slowing down from 50 mph to
20.........running it in the air, listening and feeling everywhere, I could not
identify anything. I was leaning toward rear wheel bearings, but not
feeling very solid about it at all.
Finally I pulled the trans plug out, and it had a piece of gear on
the magnet. The van's owner said to pull the trans for rebuilding.
In that process, I found a stiff rear u-joint in the drive shaft, and the
lower engine mounting stud, on the left side, broken off in the engine block. (
that was fun to fix ).
So it had those 3 actually 'broken' things, but they could not
easily be identified ( except for the gear tooth piece on the magnet ) without
disassembly. That exhaust bracket that's attached to one of the lower
engine mounting studs - I don't usually put those back on, I wonder even if
that contributes to hurting those lower stud threads.
anyway, just wanted to mention the 'swerve test' to help identify which
side bad wheel bearings may be on. It doesn't always work, but very often it
does. ( and once on a front wheel drive car, it was 'the opposite' of the logic
I mentioned above. 'usually' the side you swerve toward where the noise lessens,
is the side where the bad wheel bearing is. )

Subject: [Syncro_T3_Australia] Re: rear
wheel bearing noise???
Ken,Greg ang group.After tightening rear hub nuts and all cvs to
spec(nothing was loose),rear bearing noise was the same.I have established
that it is bearing noise and will replace them early feb.
Found another
problem though,looks like my water pump has just started to leak behind the
pulley.Looks like a real fun job.I think you have to pull crankshaft pulleys
off,stone guards,ac compressor to get to it.Monday week I will attack
that.Have always been very cautious about not over tightening the belt,but it
does look as if the pulley/or shaft has moved.Are well.By that time I should
have my decoupler from Germany to fit.Looks like I will be busy on Mondays(day
off)for some time.

Still worth double checking though.

On the way home I noticed a noise that I thought originally was tyre
noise,that seems to be in the back.It is still there whilst coasting,clutch
in,in/out of gear.It doesnt seem to be pinion bearing noise as it doesnt
change with engine speed or with acceleration. It doesnt change alot with
road speed either.
