Hi, I must replace my rear right Reluctor ring on my 2002 SC430 (rust pressure worn it smooth!) Does anyone know if I can avoid dismantling the hub unit. Is there perhaps enough clearance to disconnect from diff and push the drive-shaft etc through?

Try www.ReluctorRings.com I got a rear one: Order Summary Item Qty Each Price ABS Reluctor Ring - Lexus SC 430 Ring:48-T-799-96 1 £35.25 £35.25 Sub-Total £35.25 Handling & Delivery: First class Royal Mail £2.91 VAT £7.63 Total £45.79 ReluctorRings.com is a trading style of Exmol Manufacturing Meadow Drove Farm, Bourne, Lincs, PE10 0AL Vat No.727 7758 85 Now just looking for rear hub removal & fitting help...

Google found them a minute ago thanks & I've ordered one.

Had time to take another peek down the ABS sensor aperture. I must have been dreaming thinking I saw castellations last time I looked. As you see, the reluctor ring has been worn smooth!! That's my problem. Thanks again Andrew & Neil. I'm now on the hunt for a new reluctor ring.

Thanks Andrew. I've tried the "disconnecting the vehicle battery for a time" and I get 2.57 Volts at the ABS connector, so I think the circuit to the ABS ECU is OK. Reluctor ring secure, but Neil's link may be the answer. And thanks Neil, I did indeed have many iron filings on the sensor when I removed it, and the sensor did seem quite a distance from the reluctor ring, tho' it's castellations still looked quite prominent. It looks a massive job to replace the reluctor ring, so before I resort to that, and as I seem to have two good sensors, I thought I'd try filing down the shoulder of one ABS sensor so it gets closer to the reluctor ring! What do you think? I'll also check for rust & release the hub collar if it's grinding the reluctor ring. I'm away on hols, but will let you know how it goes mid June. Thanks again guys.

The ABS, VSC & VSC Off warning lights are lit on my Nov. 2002 Lexus SC430. Using Techstream GTS Diagnostics > ABS/VSC/TRAC > Data List, I discovered that the Rear Right Wheel Speed was not registering any speed. All 3 other wheels register a speed as I drive, but not the Rear Right. It stays at zero MPH. However Techstream did not show any DTC error codes? I assumed that the Rear Right ABS Wheel Speed Sensor was faulty so replaced it with Lexus part no: 8954524030. I reconnected Techstream which cleared the ABS, VSC & VSC Off warning lights. However, as soon as I drove a short way these lights returned & the Data List showed Rear Right Wheel Speed was still not registering any speed. The problem is obviously not the RR ABS sensor. (Both the old & new sensor show ~ 1,069 ohms). How may I diagnose deeper what the real problem is?
