UZZ32 Active Repairs |

The UZZ32 Active Soarer - the rarest Soarer of all and the best handling with Active hydraulic suspension and Active 4ws. Infuriating when not working right. Here are some stories from Toyota Imports Forum hosted in the UK.
Fixing an Active with Bounce - Greg Myers - TIF
Well my Active...which I'd nicknamed Tigger
because it just loved to bounce....has now been sorted! Tigger has been tamed!
Following Alan's recent success, I took myself up to Holme Bridge near Huddersfield to
M&M Motors where he recharged his own struts. Sadly for me not having Alan's
engineering skills I got Simon from M&M to do the job for me once there!
As they'd never done the job before I emailed all the TIF posting info and Alan had also
kindly sent me a step-by-step strut removal guide which I forwarded on.
The upshot was the job done in just over half a day and to the tune of £235.....and it is
worth every penny I promise you!
If anyone else in need of the job doing then I'd totally recommend it. (Also could be a
bit quicker/cheaper now they've done one themselves.)
Now just need Alan to get his thinking cap back on when he returns from The Falklands so
can get the fronts done too!!
Huge thank you to Alan for his help....red or white your favourite fella?
Also thanks to Peter Scott for his efforts and Paul Snape, who I think first suggested it
might be the accumulators causing the bounce, and to Smiffie for telling me where the
suspension fluid dipstick was hidden!!

Once upon a time, a long time ago, a none
member, Mr Jon Batson called me about his white UZZ32.
From memory, he had left it in a barn and when he returned it had dropped, he didn't know
what to do so he thought he would bleed the suspension out.
He then let the nipples go and all the remaining fluid squirted out, dropping the whole
car to the ground.
He then called me and I asked him to bring it over to let me see it.
It came, Mmmmmmmmm in white with lovely GOLD leather, only bettered by the Gold on gold .
Briefly, we changed the PAS / ACTIVE pump, but it wouldn't pump up, we then changed the
valve body, still no good, we changed the, ECU, Valve block sensors, reservoir, pipes,
fluid, switches, relays, modules, the accumulator, the non return valve, and just about
everything we could think of, and more.
Once we thought it was an electrical fault, I asked the owner, Jon who was an electrical
engineer to come and check out the inputs and outputs on all the sensors and associated
electrical units.
Jon spent 3 or 4 days there with his multi meter, and at the end he gave up. I still
didn't know what was wrong with it, and consequently felt so bad about not being able to
fix it, I bought it from him.
Since then, we spent another two or three weeks on it, I would say we spent about 3 or 4
months working on it off and on.
I personally didn't work on it, but I have often said to Dean, try this, remove that etc.
Today, ( after much pee taking from the Klingons) I went there with a view to spending
some time on it.
they were on it when I got there, we had tried absolutely everything, we even tried to
reverse fill on the legs but to no avail.
I think the problem is in the valve body, as we are getting plenty of pressure from the
pump and to the body, but not from the body going to the legs.
I told Dean to get the old valve body on the bench, and to start to strip it down to see
where the pressurised fluid went to once it was in the body.
We had it in 20/30 parts, and now we had a idea where the fluid should go, but no idea why
it wasn't working.
On both ends of the body were two huge allen key bolts, we undid one on either end to see
what they did, we could see a small pin prick hole through the middle but this didn't
help.
When I looked at the part we removed from the hole, I noticed it looked liked a brake
master cylinder part with seals and springs etc, I worked it out that the pressurised
fluid would press the spring and in turn open the valve to let the fluid to the leg.
Hmmmmmmmmmmmmmmmmmmmmm.
I went back to the car and told Dean to undo one of the allen key bolts from the valve
body that was on the car, it pumped up both legs on the drivers side, we did the other
allen key, and then both sides were up, yeee fooking haa.....
We let it down and it sat there, it was to high, and I had to let some fluid out to bring
it down to the right height.
By this time it was about 4:30, far to late for me to be at work, so I went home, we will
run it up the road in the morning,
I shall then fit it back together and clean it and park it right outside Koloths house to
piss him orf as mine is on the M and his is on the L. mind you his is that lovely Blue,
Grrrrrrr.
OH HAPPY DAYS -
we too made a gadget to pump oil into the legs
via the bleed nipple, and it pumped up, but as soon as the weight of the car was on the
legs it fell to the floor.
It is still up after 4/5 days.
