Freeway incident today around bend ??

[Dannyboy lx470]

Hi all wife took my car Lx 470 2001 229000 miles and while on the freeway travelling at 95miles around a sharp bend the cars steering started to swirf left and right until she straighten up on the road and press brakes. There was no warning lights or warning sounds in the car.

Recently did my brakes pads front and back and discs machined and dealer put new tyres but didn't do wheel alignment.Car drives fine no vibration and alignment is dead straight no play. Read about this on Google being a common problem on the Lx around bends but with VSC light coming on and car appling brakes by itself didn't happen tho.Some say could be wheel sensors, power steering rack (has a slight leake),or wheel bearings.

don't take turns at 95 MPH in a 6000lb high clearance truck. Problem solved.

I was wondering if speed had anything to do with it .Speed limit here is maxium 99miles on some motorways you could be right and VSC kicked in.

Just a thought, look at your steering rack bushings while she turns the wheel back and forth....

I'm dealing with the same thing right now, not as fast as you but the same symptoms.

95mph or kph?

 

[Dannyboy lx470]

155 kph which equals to 95 miles.

Read the topic could be that as I have a slight leake to leaking on the boots to.

I don't think I've ever had any of my cruisers up to 95mph and i'm comfortable driving fast... maybe 90 on a long downhill for a brief time... thinking 80-85 on long trips with the flow of traffic in this truck is about it... just never occurred to me to drive these things 100mph

I agree to.I believe it triggered it as drove on the same rode slower no issues.

Will wait, while you go see if steering racks bushing need replacing It take 30 seconds! You know how right?

Driving at those speeds you'd better have frontend in tip top shape. Or start looking for your next wife!

No .Can you please tell me or post a pick ?

Have a helper start the truck and turn steering wheel back and forth just 1/4 turns or so. Look from PS side at steering rack with flash light. See if it's moving in and out of the tie down rubber bushing in the bracket or just note movement from fix point of frame. It should not move in or out of that rubber bushing seen here with slice in rubber.

 

[2001LC]

Also watch your TRE (tie rod end) and ball joints on each side (PS & DS) for play. Check all bushing for cracking in UCA & LCA along with sway bar.

Ok will do that thank you. So basically no movement in that rubber. Which side is Power steering side ?.

What do you mean by this ?

up the insurance on the wife then you get a better truck and a better next wife

Correct no movement. What we see is the steering rack moving in and out of that rubber bushing. That means the bushing on both PS & DS are bad and need replace. White line poly steering rack bushings cost about ~$45.

PS (passage side) or RH (right), DS (driver side) LH (left) is USA left hand dive 100 series. IDK (I don't know) if you have left or right had drive. But basically the steering rack itself should not move in and out (side to side) of frame.

UCA (Upper control arm), LCA (lower control arm) have bushing where they attach to frame, that go bad over time. Ball joint tie the UCA & LCA to steering knuckle. Steering knuckle ties it all together (wheel bearings, axle, frame, steering rack & wheels). TRE attach steering rack to steering knuckle.

I would never in a million years think of driving the 100 series at 100 mph. At 85 mph in a straight line it's right at the edge of where I'm comfortable, and I sort of know my way around car control. Having spent a lot of time in fast cars on race tracks running right at the limit, to me it sounds like you were simply going too fast and got the truck unsettled somehow. I wouldn't worry about the details so much as just slowing down...

If the stability control sensed some slip and did something even remotely funky and applied a brake, you didn't have much of a margin for error. Lord, just the wind resistance on the 100 is likely enough to unsettle it at that speed if you back off the throttle. At high speed, most cars will tend toward oversteer in that situation and you're really dang lucky to have stayed on the road...
