@Chris111 do you know what alignment settings your car was set to?

Nope, I wasn't aware of such a thing and it's sounds like another tech-gone-too-far 'feature'!

How does my tracking compare with other mk3 GS450H's ?

John @Britprius, the handling is much the same, it maybe feels a bit more planted and predictable. Bizarrely it wasn't a handful before! Before...(with so much toe-out) changes of direction weren't a problem It did used to take quite a bit of concentration and input to hold a straight line. Now...I'm noticing the steering is ever so slightly heavier and now centres a lickle bit. My front toe-in is now just off straight so this makes sense. Front toe-in of 5mm overall could be increased according to the manual (1 +- 2mm) but is within spec and now I have a decent baseline to work from. Rear is now 2.6mm vs book 3 +- 2mm. Alignment ref; https://workshop-manuals.com/lexus/gs_450h/v6-3.5l_(2gr-fse)_hybrid/steering_and_suspension/alignment/system_information/technical_service_bulletins/page_8283/ The car does seem to follow the camber of the road more now and I got a pull under braking the other day. I reckon I had a low front tyre (TPMS on but tyre was okay) and the power steering occasionally seems to do this anyway. So it still needs concentration The biggest change is the comfort, riding with a full tread that isn't down the carcass...the ride is soooo much better and less crashy. I'm also back up to 35psi and it's more comfortable than previous lower pressures on the rear to try and restore some 'waft'. Fingers crossed now that my tyres won't wear so badly and will last more than 2yrs/18k miles. Heck my mpg may even go up (a bit). If you know a good garage that can do proper 4 wheel tracking then I'd recommend it, as tyres and low mpg is much more expensive than the cost of tracking. It cost my £60 incl'g the dreaded VAT AND they didn't charge me for the initial set-up when the found my OSR adjuster was locked solid. I used a specific outlet of Eden Tyre Sales (not my local) but your mileage may vary with local wrenches.

@Chris111, ah yes that also became apparent for us recently. We sat the full size upright in the boot and everything else was dumped on the back seat. Not ideal but thankfully there were just 2 of us. But in hindsight we should have put all of the boot back (wheel support, floor, suitcases, etc) and then just put the bad wheel on the back seat. Other than this I can't remember the last time we had a flat. Lets hope we don't have another soon.

+1 to this, I recently had a flat and didn't have a suitable tyre iron/lug nut wrench/wheel nut wrench call it what you will. Not having the right have spanner caused us to wait over an hour for recovery but we could have swapped the wheels over and been on our way. Lug nuts are often over tightened by tyre shops and their 'windy guns'. I always re-torque mine afterwards so that I can get them off with my own spanner (which I have since added back to the toolkit). Ha, I often have a panic as to where I last left the locking wheel nut. Friends have suffered from tyre shops/dealerships not putting their locking wheel nuts back in the car and only finding out during a breakdown, this gets expensive real fast.

On mine the bush goes to the top and I suspect yours will be the same/similar. Ref; https://lexus.7zap.com/en/eu/lexus+gs/334510/gws191r-bexqhw/2/4707/476476b/ Let us know how you get on. Oh and welcome to the forum, how long have you had the IS200?

It's a shame the top mounts are so long but once you get bottom mounts in place then it'll secure it nicely. Adding the pipework will add more bracing, so that cooler isn't going anywhere. Good work.

Haha, true...don't they call it 'character building'! All sorted now tho [emoji41]

It doesn't take much water to get in for it to feel like you're bought a cabriolet! So I'm hopeful that you only have a small leak that has been occurring for a while, or has suddenly got worse. Hopefully removing a blockage will cure your leak, fingers crossed as it's all speculation until someone dives in to check it out. Drying out the car will be a slow process, folks have been known to pour in bags of uncooked rice to soak up the water (it it's that bad). In the meantime, to reduce more ingress is the car parked inside or under a car port?

Crumbs, that's a low mileage motor - well found. Any chance of pic's? 'as new' condition' so no apparent issues/niggles to work though?

Well done investigating the issue a bit more but chin up, it's not a major mechanical issue and a decent/honest/hard working garage should be able to sort it out for you without breaking open the children's piggy banks. I feel for you though as once the leak(s) are fixed then it's going to take a good while to thoroughly get all the carpets/etc dry. Personally I'd work through the niggles and then you should have a good runner. If you jump ship then you're likely to take a loss selling this car and then have to shell out for another which might turn out to be in worse condition. If you were closer, I'd happily take a look for you...maybe another forum member is closer and happy to be fed/watered while they help you

Ah okay, at least you got a discount Try tracing the leak to it's highest point if you can. It could be something simple like a torn door seal.

Welcome to the forum and I'm sorry to hear that you had a few surprises on the drive home. Did you buy the car privately or via a dealer? If it's the later and these issues weren't evident during the sale, then the dealer should resolve them. Water ingress is a matter of tracking the water from it's highest point and will inevitably need some panel removal to investigate. Front wheel wobble suggest a poorly balanced front tyre, which can be easily checked at a tyre shop. For the EML, do you have a OBD scanner/software to read the error code(s)? Cheap readers can be sourced online and many code reading software can be found for your phone. I hope you resolve this issues easily and with minimum grief. Otherwise, is the car all that you hoped it would be?

That looks great, well done [emoji106]

Before and after alignment, on a Hunter Hawkeye

I don't recall seeing any stamps/etc that were near the coast. I'm in the midlands so it's only road use that can have contributed. I've been under many cars of various marques/models that have been UK daily drivers and all have shown plenty of rust. Even newer cars, say 3-4 years old. The plastic under covers/trays can hide alot. The rear subframe, front covers came off for this job and they are hiding lots of corrosion. So i definitely need to get the underside property treated in the New Year. Tracking has been sorted and the car seems to coast longer on battery [emoji106] All 4 corners were toeing out quite badly, even the fronts which is annoying. As the shop claimed they adjusted them when we recently fitted new rear tyres. Grrr. I set the new rear bolts in the middle of their adjustment and that gave a whopping 15mm+ toe out [emoji44]

Ah that bring back memories, wriggling all the parts into place and getting everything to line up around a bigger intercooler. Looking good though, well done [emoji106]

I swapped out the easier NSR today during lunch, the bolt hadn't seized up so it popped right out A dose of hail wasn't on the forecast tho Nipping up all the bolts and now the adjusters work a treat I'm booked in for a 4 wheel alignment tomorrow afternoon.

The '06 didn't come with a lithium battery, extract from documentation "Sealed, Nickel-Metal Hydride (NiMH) modules, 288-volt". I've seen literature in 2013 that says Lexus weren't going to Li-on. Due to cost and how they handle overcharging (via heat). When do you think they changed to Lithium?

You seem to be referring to the big expensive traction battery and not the regular 12v 'puter booter right? Several folks I've spoken to have said the traction batteries are usually good for 130k/10 years+, so yours should golden for a while yet. If it ain't broke, then don't fix it.

The OSR toe bolt/arm put up quite a fight but that side has now been renewed I had to resort to the angle grinder in the end, it's really right and awkward too. Just the other side to renew now but that was loose so 'should' be much easier, famous last words!

Some vehicles have filters on the pumps within the reservoirs, which can become gummed up and lower jet pressure. I don't know if GS's have such a filter/gauze but I wouldn't be surprised if they did. It could be that the previous owner put or left some odd concoction in the tank, that's now turned gloopy in the colder weather? Maybe try putting some boiling water in the tank and pumping it thru to see of that helps? Did I read that adding a touch of vinegar could help disolve any gunk? Verify this first tho. Good luck and let us know how you get on.

Hi Phil, welcome to the forum and becoming a gold member As you car is silver it must be easier to keep clean than mine! What niggles do you have? Cheers, Lee

Yes, I was susprised to see grease ports but think it's a great idea and will lube 'em annually alongside caliper sliders during my service. It's a shame there aren't grease ports at the other end 'cos that's where mines locked itself to the bolt You can't have everything tho as they didn't come with rubber caps so I need to get some ordered.
