I recently bought a GGH20. It came to me lowered, on coilovers, and the ride was way too stiff for my liking, as well as the front airdam touching down regularly and making a hideous scraping noise. I raised the coilovers to full height, which was a massive improvement, presumably because it allowed the dampers to use their full stroke without hitting the bump stops. However I then noticed that the gap at the nearside rear wheelarch was less than that at the offside rear. The spring on the low side was not broken, so I assumed that it was simply weak, so I took the plunge and bought a whole set of new, standard suspension. Annoyingly though, after fitting the stock springs and dampers, the difference in the wheelarch gaps at the rear remained as it was. So it just goes to show one should never assume! Could it be a problem with the torsion bar? I'm aware that some torsion bars are adjustable for ride height on either side. Is the Alphard's? I know nothing at all about torsion bar suspension, so I'd appreciate any feedback. Could it be a failed bearing or bush? There's nothing in the way of unusual noise or sensation from the suspension.

This is superb, thank you. I'm very grateful. Am I right in thinking that the 'SST' (Special Service Tool???) used to jump the pins on the OBD connector is just a piece of wire? I can buy one from Amayama, but it's going to be £50 including delivery! https://www.amayama.com/en/part/toyota/0984318040

There seems to be no way to adjust it. Is there a way to adjust the base level at least? Maybe somewhere on the back of the light units themselves? I can't see anything obvious. It supposedly has self adjusting headlights, which are controlled, I believe, from an adjuster connected to the rear suspension. Now as it happens I think there is an issue with the torsion beam, in that the near side of the car sits way lower at the rear than the offside does. It's definitely not the springs, as I've just put 2 brand new ones on and it made no difference whatsoever to the issue. So this raises some questions: 1. Can I adjust the lights, either from within the engine bay or somewhere else? 2. Can I adjust the torsion beam so that the load at reast is even across both rear coil springs?

The same gearbox is in contemporary Lexus models like the RX, so a Lexus specialist might be a good place to start?

I only just noticed these replies, sorry. Other forums I'm on email you when there's a reply to a thread, but not this one, unless I've missed a setting or something. Anyway, on my Alphard, what appear to be reflectors in the rear bumper are actually LED lights (maybe they are both reflectors and lights???), so they are already wired for power, but I would say that they are not sufficiently bright to be a foglight.

Hi All, first post, so be gentle! I recently picked up a newly imported mk2 Alphard 3.5. It had been MOT'd without a rear fog light. The importer says he has a 'temporary fog light' which he fits for MOTs and then removes, but that seems fishy to me. Anyway, the long and short of it is that I need to install one. I've ordered the right switch for the dash, but I'm looking for handy hints regarding the lights. What method has the most ease of fitting, least cutting/drilling (preferably none!) etc. Cheers.
