When I drive over rough roads, the steering column vibrates and I can hear a rattle (as if the steering rack bush was not there).

I replaced the steering bushes, including the center one.

Any ideas on how to better diagnose or what to look for ?

Thanks

Hi Chris, Mine's the same, and I have plenty of rough roads in Tanzania to test it on! I have come to the conclusion it's the adjustment on the steering rack - ie how tightly the rack is adjusted up to the pinion. When I replaced the oil seals in my steering rack I adjusted the rack very lightly (as specified in the manual, basically just losing the play between the meshing teeth) and the noise on rough roads disappeared for a short while. Now it's coming back, so I think I need to tighten it up again. The adjustment is accessible on the rack from underneath the car. If too much play is allowed I think it causes the oil seals, especially the nearside one which is furthest from it, to fail. Have you checked if your oil seal is leaking? It can leak into the boot and you don't know until you take the boot off.

What about your control arm bushes?

I had similar issues which I assumed was coming from the steering column. I replaced the rack rubber mounts but the problem was still there. Turned out it was the front left shock - the airbag was fine but the shock itself had worn out. A new strut fixed the problem.

Thanks guys.

Front shocks are new, lower control arm bushes were done 2+ years ago.

Not sure how to get to the rack adjustment or the seals. I need to get under this weekend, changing the oil & filter.will have a look.

Many thanks again for the feedback, always so valuable having the forum and the members who participate.

Hey Seamus, a Soarer V8 in the mountains. Please tell more.

I came across my Soarer by chance, Chris. Most vehicles round here are 4x4s as you'd imagine - I also have 2 landcruisers, an HZJ80 and an HDJ100, but the Soarer is great when I have to go to meetings in Arusha, a town 75 miles from here. The road from here to there is good, and I was looking for a smaller car for commuting when an acquaintance offered me the Soarer. He'd just imported a load of vehicles from auction in Japan and I think they threw in the Soarer as a discount bonus! It was in great nick, still is, but he couldn't sell it because of the engine size and the fact that nobody would know how to service it. I bought it because I loved the look of it and wasn't frightened at the prospect of fixing it. So far I've replaced the air struts (had a Japanese friend importing stuff from Japan and he slipped them in for me!), changed the timing belt, water pump, radiator (it blew up on me!), overhauled the power steering pump and the steering rack, and the alternator, and my next job is to fix the dash as the bottom line hardly ever comes on even in the warm weather here. But it's just such a lovely engine!

Sounds great.

Tell me Seamus, when you imported the air struts from Japan, were they in reasonable condition and do you recall how much?

What do you do in Kilimanjaro ?

I imported them brand new! My Japanese friend ordered them direct from Toyota and they cost about US$200 each from memory. I contributed about $200 towards freight and clearing so the set cost about $1000. Not cheap, but had I bought them from the local Toyota dealer (who would have had to import them specially) he was quoting over twice as much. I think that if I'd not had my Japanese friend to help, I'd probably have bought Supra struts from the UK and just scrapped the air suspension system. I was having problems with the front struts in particular, before I changed them.
I work in tourism here in Tanzania. We have a family hotel on the slopes of Kilimanjaro and we send people up the mountain - just sent 10 this morning.

Well, Ben, when I was a kid you still saw a lot of antelope and giraffe etc on the open roads around here. My father used to go hunting at weekends just 10 miles from here! But with the xplosion in the human population the wildlife has retreated more and more. The roads around here are now dangerous because of drunks (both on foot and behind the wheel), stray dogs, cattle and goats, and Masai donkeys - even the big lorries slow down for the donkeys, they'll completely destroy a car, even more so than a cow. But the upside of the population growth has been an improvement in roads and in this area they are smooth, fairly wide, and with lots of open straights so it's easy to hit the limiter on the soarer without trying. Not many radar traps either! But if it's elephants you want, Ngorongoro Crater is 6 hours from here, and the Serengeti is another 3 or 4 beyond there. Nice place to live!
