Just failed an MoT due (aside from a bit of welding to do by OSF jacking point) to steering box leak.
Why would a steering box leak? Are there seals that go? Do i need a new or recon box? Big job?
Not a happy bunny. :'(

It's filled with PAS fluid, so can obviously leak. I'm sure seals could be replaced, but the factory workshop manual would say replace steering box.
Loads of Omega spares about, so shove on a known good one, once you've checked it is coming from the box.
-
Gearbox cooler lines are in the same location and can corroded, like wise the power steering lines.
And as they all use the same fluid, it's not a surprise that any leaks in the area will be presumed to be the box as it's bolted to the rusty part that all the rusty pipes run over.
-
And it has to be dripping to fail not just oily.

If you're really lucky**** it will have been leaking long enough to prevent the steering box mount and surrounding metalwork from corroding.
**** You won't be

It is, allegedly. :'(

I've just re-built the steering box on the LC. In order to practice first, I bought an Omega steering box from eBay and stripped it down. Think it was about £30, and it came with the steering arm and centre link still attached. I was hoping that some of the parts, perhaps even the complete steering box would fit the LC, but unfortunatley everything is just a little bit different.
Assuming it's not just the PAS fluid input/output pipe junctions that need tightening up, to leak to the outside world there are only really a few places it can do so.
1) Bottom of the steering box - where the steering arm is. There is a lip seal on the output shaft here.
2) Top of the steering box, under the alloy plate with 4 bolts and the tension adjuster. There is an O ring under here.
3) Junction of the PAS pressure box and the main body - another O ring here.
4) Under the PAS pressure modulator Servotronic solenoid. Couple of small O rings here.
5) Steering column input shaft. Lip seal here.
You can probably replace any/all the the O rings in 1 and 4 without a complete strip down - perhaps even with it still in the car. However the two lip seals will need pressing out, and to get that far you really might as well replace everything
So it all depends exactly where it is leaking from. A complete seal kit is available (from Bulgaria!) on eBay for about £70. That doesn't include the 3 bearings - two of which will need to remove - they will be another £100 or so.
In short - I'd probably throw another second hand PAS box at it. Will be cheaper and less agro. Try to get one from exactly the same spec Omega - there are lots of subtle changes, and even different length of steering arm. You can swap the arms from one box to another, but they're on effing tight and you will need a decent puller, and probably some heat to persuade it to come off.

Anyone know the GM part number for my 2.6 steering box? ???

as advised by the good gentleman LC0112G ....
you should try and match the part number fitted already ;)

There are at least 8 RHD part numbers. Can't narrow it down without a lot more info, so you really need to get a part number of the current unit.
Does your car have servotronic variable assistance power steering? If it does, there will be an electrical connection on the side and a square box solenoid - like this...

If it does not, then there isn't an electrical connection, and no square box, like this...

Thanks guys. The car is stick at the welders as they wanted to do a small bit at the front while they had it. Thus, I can't go and check part number etc.
Should get it back later this afternoon, fingers crossed.

Got the car back. Welding all done. :y
Found the part number (yes, it was easy after wiping the grime away!), it's 8052991124.
Just need to find one on the interwebby thing...

After welding and applying a bottle of Lucas Power Steering Stop Leak (good stuff!), got a new MoT. :y :y :)
Have a replacement secondhand box coming – just in case. ;)

Brilliant news. I would just clean off the box with parts cleaner and see if any leak returns. It could have been the most minor of seeps accumulating over the years …. :y

Too old to crawl underneath to clean it, but point taken, James! ;) ;D
A replacement box has now arrived, so I will keep that in stock...just in case! :y
