Am I on the level -- or how do I check ride height?

G'day all,
yesterday when I filled the wee beasty to 3/4 of the tank of fuel and, I noticed that the gap between the top of the front tyres and the fender had increased and at the rear decreased. To me that indicates either the ride height (SLS) is not working or is in need of adjustment.

I would be grateful if you could enlighten me as to how to check this and adjust to correct settings.

Or what do others do if this (SLS) is a problem?
yours aye

Hi John - here you go:

If you work under the car, be very sure to have plenty of clearance as operating the control valve manually can lower the car...

Note the valve has a bleed point if you ever need to do any work on the SLS.

Thank you all for your assistance., I now have the SLS working and reset to 570 as per factory.
I now need to run it for several days to locate where the slow drip is coming from.
Yours aye

Fluid loss occurs where the 3 hoses attach to the reservoir. If the area below the reservoir under the car looks wet...

One of the hoses is a small diameter and hard to see or reach. Remove the left air box/MAF assembly, then release the oil filter housing mountings and move the housing into the new space. Then release the reservoir mountings and you will be able to reach the clips, but cut off any soft sections of the hoses first.

G'day Chris7,
I have replaced all the hoses that go to the fluid reservoir located front left of vehicle just above the wheel well, all the hoses suffered from going soft at the connection and had loose clips, they had been cut before so there was not enough to re-cut. I ordered new hoses and replaced the doggy ones. No fluid leaks from that area now. But I have a very small drip from the area of the SLS valve at the diff area , I think its coming from where one of the unions goes into the threaded part. I have tightened all the lines that go into the SLS valve, so I now will wait and see.

Tomorrow is replace the noisy , very noisy fuel pump, it's probably still the original pump so at 230,000 k's it's preventive maintenance. I ordered and received a VDO fuel pump for the job.
Cheers my friend, trust your well.
