@Daveyboy20 Quote: " Posted October 30 I think the thread is a little confusing as there are 2 cars being spoken about.. To clarify: Mine is a '98 LS400 It has had wheels balanced recently, but the tyres are quite old and worn. It only happens at speed (55-75ish) High speed braking had a brake pedal judder. Round town it's fine. " How old are the tires?

wheel type: 54007001 ...introduced by O.Z. for Lexus in 1994 for 95 model 17" [8Jx17 H2] the offset is ET40

Regarding Removing Spark Plugs: - Remove spark plugs on an alloy engine only when engine is cooled down. - Do not use anti-seize on spark plugs. Put them dry back in.

Please, keep us updated on that matter.

Wow. Never knew that the exhaust system came with & without (W/O) catalytic converter option. Good to know.

Look for high temp FIPG and do not use the cheapest stuff! Sealant black - Oil Pan:...................FIPG - Formed-in-place gasket oil pan bolt: 12 x 7.5 Nm FIPG 00295-00103 (250 grad celsius) Alternative: not that expensive: K2 Silikon black (300 grad celsius) or Beral High Temp FIPG (that works superb on mine for almost 5 years now).

Colour code is under the hood. It looks like: Code: LE01 (tan ivory)

How about repairing starter - solenoid contacts and plunger?

There you go:

How about fuel pressure? Looking for leaks is not checking capacitors. Just sayin'. All electrolytic capacitors with non-solid electrolyte age over time, due to evaporation of the electrolyte. The capacitance usually decreases and the equivalent series resistance (ESR) usually increases. The normal lifespan of a non-solid electrolytic capacitor of consumer quality, typically rated at 2000 h/85 °C and operating at 40 °C, is roughly 6 years. It can be more than 10 years for a 1000 h/105 °C capacitor operating at 40 °C. Electrolytic capacitors that operate at a lower temperature can have a considerably longer lifespan.

For DHP wheels 245/50R17 would be the best size. I suppose most people go with size 225/55R17. MK III: 225/60R16 245/50R17 225/55R17 225/50R17 235/55R17 100Km/h 99,94 99,57 102,98 97,99 OE 0.06% too slow 0.43% too slow 2.98% too fast 2.01% too slow I recommend: Vredestein Quatrac 5 - 225/55 R17 101Y XL (B/C/70)...2tires/215€....HP high performance ...new in 2014 front rear All Season tires 2,6 bar 2,8 bar

Starter-motor-solenoid? Look for starter repair kits on UK-fleabay (repairkitsuk). Superb quality.

Wheels definitely are Platinum Edition and that is a special edition in the US.

Here is some info regarding DHP option.:

It's an old thread but who cares. If someone is looking for a good high performance all season tire I recommend Vredestein Quatrac 5 - 225/55 R17 101Y XL (B/C/70). Introduced in 2014 and tire pressure is 2,6 front/2,8rear.

Nice pics but have you checked engine coolant yet? It looks a bit low. Greetings

INSPECTION FRONT LOWER BALL JOINT...................There is no need for a pry bar.

Just another hint. Where to look for part number and location: UK-model Europe RHD year '94: http://www.japan-parts.eu/lexus/eu/1994/ls400/ucf10r-aepgkw/4_431210_005_/body/7701_fuel-tank-tube/2

My car (RHD-UK-model '97) is fitted with it. How about earlier models? Let's find out and confirm. PS: I look for and take every LS related repair manual I can find....:o)....

A repair manual is such a wonderful thing to have, isn't it? EVAP system UCF10: EVAP carchoal canister location UCF20 (model year '95-'97):

Got a diagnostic code yet? Check your car's evaporative emission (EVAP) control system. - visually inspect charcoal canister - look for cracks or damage - (could be clogged) check for clogged filter and stuck check valve and diaphragm You will find procedure in the repair manual under Emission Control. Blockage preventing the tank from properly venting. This could be due to a plugged charcoal canister or canister filter, a stuck closed canister close valve, or any sort of blockage in the evaporative system.

What Landsail model do you run on your LS400 and does it have M+S label?

That sounds like: 89221 - COMPUTER, MULTIPLEX NETWORK BODY Repair Manual from a 1997 LEXUS LS400 (RM514U) / DI–594 DIAGNOSTICS – MULTIPLEX COMMUNICATION SYSTEM Matrix Chart of Problem Symptoms: Key Reminder System Headlight and Taillight System Illuminated Entry System Seat Belt Warning Power Window Control System Power Tilt and Power Telescopic Steering Column Power Seat Control System Power Mirror Control System Power Door Lock Control System Headlight Auto Turn–off System Wiper and Washer System Power Shoulder Belt Anchorage System http://www.japan-parts.eu/lexus/gr/1996/ls400/ucf20r-aepgkw/5_431220_005_/electrical/8401_switch-relay-computer/3#89221 The culprit might just be some corrosion on the connector plug!?

I do not know if it will fit. Looks the same, but it's got different part numbers. 1996: http://www.japan-parts.eu/lexus/gr/1996/ls400/ucf20r-aepgkw/5_431220_005_/body/6705_rear-door-panel-glass/2#67003 1999: http://www.japan-parts.eu/lexus/eu/1999/ls400/ucf20r-aeagkw/3_431220_010_/body/6705_rear-door-panel-glass/2#67003 Toyodiy says it will fit: 67003-50905 Europe, General 10/1994-07/2000 LEXUS LS400 UCF20 67-05: REAR DOOR PANEL & GLASS http://www.toyodiy.com/parts/xref?v=E_1996_LEXUS_LS400_UCF20R-AEPGKW&s=67003-50905&mU=on&mE=on&mJ=on&mG=on
