We had an instructor who was THE idiosyncratic of the training school. He would cook a raw sausage by applying 240 with 2 nails as scewers each end,..I kid you not! He'd apply some pulse-width modulation by switching the ppoint on and off as things sizzled along... Jason

Even at a standstill idling the power steering belt v-belt in older cars has to be fairly tight to avoid slip, cold startup especially. I wouldn't be surprised if the drag was similar to an alternator under load. I guess someone somewhere has got figures. Al -- I don't take sides. It's more fun to insult everyone. http://kwakakid.cjb.net/insult.html

Just to follow up on this, I just checked my paper stack (we're saving them for wrapping at the moment as we're packing boxes for storage) and I've still got the paper. It's pretty much as I told you. Two paragraphs at the bottom of page 8 and the details are correct. The only detail I had wrong was when it appeared in the paper. I thought it was last week or so, but it was actually closer to a month ago (it's been a busy month :) The Herald-Sun's website doesn't list the story exactly as it appears as "fill" in the print edition, but they have a more elaborate version here: http://www.heraldsun.com.au/business/toyota-worries-extend-to-steering/story-e6frfh4f-1225831711268 And News.com.au features a similar story (obviously from the same source) here: http://www.news.com.au/business/toyota-could-face-corolla-probe/story-e6frfm1i-1225828548892 After reading through those more detailed reports, it would seem the problem is worse than the original print story made it out to be. -- Regards, Noddy.

If that is the case, it is safer in an "assistance fail" situation. The motors simply stop applying torque and the steering reverts back to a std unassist steering. That's my theory. In a hydraulic situation, the pump stops turning and the Left-Right valves may just shut, meaning you'd have to overcome *that* resistance before your arms can effect steering? A lot of assumptions there, I know. Jason |
