Possibly killed a wheel speed sensor, did the garage use the hammer in type ball joint splitter?

Thanks Steve, didn't need to use a splitter the ball joint was already  in two parts with the wheel jammed in the wheel arch

I took the ISF down to Cornwall at the weekend (180 miles each way). The Mrs drove the first leg, and I couldn't help notice that she seemed to be making lots of tiny corrections to the keep the car pinned bang in the middle of the lane.

When we swapped seats, I found the steering rather odd as well. When waited up with just a few degrees of turn left or right, all seemed fine. However, on the straights it felt jittery - almost like there was a numb point either side of dead centre. 

I stopped and checked the tyre pressures - which didn't seem to far out. Unfortunately, the rest of the journey was twisty A roads, so I was unable to tell if the problem had been fixed.

On the return journey, I noticed the problem again, but also spotted that there was fair old bit of wind - cross winds.

I'm want to believe that maybe the car is just susceptible to crosswinds, but I'm really not sure. OR maybe we were imagining things!

I'd appreciate your thoughts.

Cheers.

Got a 2003 GS300. Had a similar problem. Got it on a ramp and my mechanic checked it over, no sign of any wear in the steering parts or suspension.

Over the course of time I replaced front shox, all brake rotors and pads, tyres all-round. Tracked and balanced twice and the problem persisted, got worse

even.

Last Tuesday driving at 80 kph on a country road kapow, crack the front driverside steering ball joint let go, bit scary. Slithered to a halt after about 100 meters.

Got away with ball joints * 2 (replaced both) , new tyre (old one left it's rubber on the road), tracking and a slightly bent wing. Steering, braking suspension are lovely now.

Ball joints are cheap (about 140 a pair ) and easy to do, but make sure you get it tracked.

My only problem now is that I've got the 'ABS', ' VSC' and 'VSC off'  lights lit up all the time, with no diagnostic codes found. Tried the paper clip trick to no avail. Any ideas anyone ?

Many thanks Colin, makes the fix much more simple.

Did a bit of research this morning, I take it that I'm looking for lambda oxygen sensors like in this link ;

Quite new to my Lexus, anyone got a diagram as to where I can find these sensors.

Thanks

Yay , just replaced the front centre anti-roll bar bushes and not a thump or grumble to be heard. Success.

Only problem now is I've got P0135 & P0141 fault codes (O2 Sensor Heater Circuit Bank 1 Sensor 1 / 2), groan.

Like many on this forum I have a slight knock on poor roads in my GS (2003 300 sport). Replaced shox, discs, pads etc. My mechanic can find no wear on bushes, ball joints etc. Had a 190 merc some years back similar annoying knock. Replaced everything at great expense no solution. Turns out that it was the engine mounts were a bit worn, so it might be worth checking out engine transmission mounts on the Lexus. By the way I've had a long line (25 odd years) of Mercs, still have a 190e and a classic 350 slc but as a recent convert to the Lexi, I'm hooked.

Tried any breakers ?

I've got a 2003 GS300 sport, had the same story. Replaced all tyres, got worse. In so far as it was intermitant I figured it might be front brake related so I shopped around and bought new front discs and pads (less than 90 euro at http://www.mister-auto.ie), fitted them, and it's perfect. Worth a shot at the price.
