Having looked long and hard for the servo on the box it's clear any work in that area is going to be a total nightmare.

Change pump first.

[Andy H]

Damper loosened. Good half turn. Eeeeyerchh not nice to drive at all, loose and unresponsive dead ahead. But crucially no different lock to lock. Re adjusted to where it was. Can't see a problem there...

I can't find a good photograph of the steering box. This one only shows one adjustment.

By it's location it has to be the sector shaft height adjustment. It should be adjusted so that there is a tiny amount of play at the tight point (which should be straight ahead, but might not be).

Too loose and the steering will be diabolical (as you discovered).

Too tight and immense forces are imposed on the components in the steering box.

If someone has been messing with the adjustment without understanding its purpose I don't think I would ever be totally confident about that steering box again


PS this photo was of my old 1994 2.5 V6 CD. I cannot see any servotronic gubbins but I don't know if you would see it from this angle

As far as the damper adjustment goes, there's no problem there.

[feeutfo]

Servo is directly under the two pipes bolted to the side. Behind the heat shield.

As you can imagine, with engine in place, somewhat tricky to get to. ESP as there are a load of LPG pipes routed found the back of the engine, and straight over the top of the damper adjuster nut and the servo.

Good pic though.

In fact, I think that's the wires too the servo plug, going down behind the brake pipes.

[Andy H]

I can see how access might be a problem

[tidla]

Just hurry up and come up with a solution so i can fix mine.

(parts fitted so far, pump and relay)

[feeutfo]

Ain't going to be for a while. Sadly. I'm on 12hours for a week and a half. 

Does anyone work for a company that can organise a piss up in brewery...?

But as you've changed the pump...
If you fancy a look at the servo, on mine there are two nuts holding the heat shield to the steering box accessed from undernieth, and a 10 mm nut from the top. Under there , from the top/engine bay I'm sure you'll see the servo, under the two power steering pipes.
 
4 small Allen key bolts to remove... And I'm not sure what happens next... ?

[Spireite]

It's actually 2 x 2.5mm cap bolts, diagonally positioned, other 2 bolts are to hold solenoid together.  Absolute git of a job, need a 2.5mm Allen key, but mine were so tight the Allen key snapped, so game over. I sourced what might of been the only remaining solenoid in UK for £55 new from Vauxhall parts specialist who buy up ex stock dealerships.

Expect to part with nearly £200 from Vauxhall, on order from Germany, and waiting time. They are available in USA for cadillacs, but again are couple of hundred dollars.

Attack job from top mostly, remove heater matrix pipes is a must, heat shield can damage wiring to solenoid if not careful as I found out, needs bending and removing from underneath.  Working room is non existent, may try 2.5mm hex bit using a ratchet spanner. Bolts x2 only meant to be 2.5 ft/lb but mine were tight enough to shear Allen key.

Will have another go soon.

Best of luck.

Hi Dean, do you know which two bolts to undo to remove the unit? As opposed to the two that hold it together...?

Luckily I have a bit set and adapter to work with a ratchet spanner.

[Kevin Wood]

Why are we still considering the solenoid? IMHO, that has been proven to be working as expected given that the steering is heavy in places but still affected by removal of the servotronic box.

IMHO, stiffness in certain parts of the steering travel while the pump pressure relief valve operates points to the box, although there's an outside chance that the pump relief valve could be opening early. I don't think I'd be struggling to get to the servotronic valve given what we know of the problem.

I'd be swapping the pump with a known good (just because it's easy), then it's the box.

[TheBoy]

I agree with Mr Wood.

Kevin - I think gayboy is delaying it until he has more cutting discs for his grinder, you know how he has to saw everything open when he takes it off

Well, the steering box will keep him out of mischief for a while.

Well, if there is a demo being shown...
