Picasso Posted August 27, 2022 Share Posted August 27, 2022 I would have the rack checked there are 4 bushes pressed in to the rack these are common to fail on the earlier alphards that would give you lot of play in the rack Quote Link to comment Share on other sites More sharing options...

arthurj Posted March 6 Share Posted March 6 So it’s not coming through the pedals, but I have some rattling of the steering column. There was a post the other day on one of the Facebook groups that suggested this is a common fault with the 20 series, but I’ve not heard of that before.

Quimbasher Posted June 13 Share Posted June 13 I have been chasing a steering rattle since I bought it months ago (GGH20). first port of call to replace the steering motor damper, but when I removed the power steering motor it had already been replaced, possibly by import dealer. next I checked the steering column and felt movement possibly from the U joints. Bought a new but cheaper than OEM intermediate shaft off the bay and it helped a little but still a bad rattle over rough road surface at lower speeds. So after researching its been noted that the large gear that mechs with the worm gear from power steering can wear. so I stripped it down and greased the two gears. This quietened it down massively, but only lasted a week or 2. As a result I now know its the steering column at fault, so have ordered hopefully a genuine new column minus the motor, from Japan. From what I have read this is common enough, though the previous owner of mine lived along a Stoney lane so this may have been a contributing factor Quote Link to comment Share on other sites More sharing options...

arthurj Posted July 23 Share Posted July 23 (edited) I have the same issue. Almost completely certain this is the issue. Mine sounds like it’s just starting, only just noticeable so it’s a job for next year. https://www.youtube.com/watch?v=TU3IeGh8kMw Those little bushings can be found on Aliexpress for £10. Way cheaper than replacing the whole motor, but beyond what I’m comfortable doing myself. Edited July 23 by arthurj Quote Link to comment Share on other sites More sharing options...

I am now rattle free! Quote Link to comment Share on other sites More sharing options...

I am now rattle free! Did you find it an easy job? I want to try replacing the bushing, or at least seeing if it’s the problem, but I don’t know if it’s something that should be attempted by someone who isn’t a qualified engineer. I’m pretty handy, have some experience with motors and electrics and can do normal car maintenance, but I wouldn’t call myself a mechanic.

Quimbasher Posted August 31 Share Posted August 31 (edited) It wasn't a difficult job, just awkward. I know Ben Hau can replace the unit as a service, hes on the facebook pages. end of the day its just nuts and bolts, its not cheap even doing it yourself. IIRC the column was £560 delivered. on some videos showing the bush change they remove steering wheel but that not necessary, just drop the column down and unbolt the power steering motor. i believe if its driven with a failed steering motor bush for too long the vibrations go into the column and cause the wear. so if you hear the steering rattle get the bush checked asap, its only an £8 part.
