Hi there. Same car, same problem for me - 2005 RX400h SE-L, flashing AFS light. Found a YouTube video showing the linkage on a different Lexus model, but haven't yet tried to find it on mine. Useful info on the Derby company - thanks!

Hi there have you given ian a ring at Roys motor company in norwich? He may be able to help, I know they had a similar issue with a lexus sc430 which they sorted. I always go there for my servicing etc they are excellent and have been looking after lexus and toyota for over 25 plus years, may be worth a call be fraction of cost of lexus.

If any one needs one of the linkages PM me as I have some made up.

This is just the linkage not the whole sensor assembly which does cost ££££s

 

Link below shows the part.

Not sure of the size you require but very easy to make your own, you can buy various size ball joints and threaded rod from places like RAPID, RS Components or FARNELL.......similar to this

Can anyone tell me exactly where this sensor and linkage would be on my RX400h 2005? I'm getting a couple of new tyres fitted later and would like to take a look under the car at the same time. Thanks all.

Off side rear suspension linkage mate. If you take of the wheel you can see it.

It appears all you need is two ball joints and a section of M5 threaded rodding, as above go to "rapidonline" the two joints and half a metre of threaded brass rod will cost about £6..............or tell me the length between locating holes and I'll sell you one for £50  :winky:

Thanks for that Boxbrownie!

I should be able to get the brass rod in B& Q and I might be able to salvage the joints. I don't know the part code for rapid online!

It is not urgent as my local garage did a "repair" a while ago for the MOT, but I don't know how long it wil last.

 

I had previously joined the 2 parts of the broken rod with a piece of electrial type shrink wrap rubber.

That went through 2 MOT's without being spotted, but on the 3rd year he spotted it and passed it provided I had it fixed properly :)

Amazingly the headlamps had stayed in alignment  all that time while the rubber did the flexing and the top ball joint  was seized up!

This is not to be recommended :)

Rapid Online

 

51-1692 M5 Steel Ball Joint @ £1.96p each  (2 off)

50-8911 M5 Threaded Brass Rod 500mm @ £2.20p each (1 off)

 

There you go.......well worth having a go with these first, unless upon inspecting the original component you feel 5mm is too small, then there is always the option of using larger balljoints/rodding, but for moving a linear switch I would think these will do fine.
