Loose steering feel

Unread post by ravofireman » April 3rd, 2015, 7:24 pm

Gday Guys

I have a 1992 v6 4runner,

Any ways the steering feels loose and bump-steers all over the place, I have jacked it up and cant seem to find any majour movements in any parts, I am wondering if this is common in these,

I am thinking of replacing every thing in the steer department but thought i would ask first,
Thanks

Given that there is no obvious wear in the linkages it could be the steering box / rack itself

Place your hand on the top of the steering wheel (TDC) and turn the wheel left and right slowly while sticking your head out of the window looking for when the front wheels actually start to move - the legal maximum of "slack" , IIRC correctly , is 100mm ( that includes 50mm either side of TDC )

If its greater than that its probably wear in the steering box / mechanism itself - grab a workshop manual and adjust that movement out to about 20-25mm either side of TDC ( don't overadjust or you will be steering the vehicle every inch of the way - enough is good - too much is bad )

If all else fails give it to a front end specialist

too much toe out will do it too, get it wheel aligned

It looks like you have wide rims. Hard to see.
That will cause bump steer of the vehicle with everything in perfect order. If anything is a bit maladjusted or worn, then it will be worse.

A bit too much toe IN or OUT won't alter the steering characteristics very much and won't affect bump steer.

Toe in/out can easily be seen if way out of whack.
if it has been raised by some method ie, normal or shonky, the vehicle has a higher centre of gravity and then the shocks must be better to control the body mass on bumps so the bump doesn't alter the steering much.

Maybe the rear suspension spring/link bushes are worn out, and looking at the front isn't going to find loose and floppy rear axle movement at all. If the rear axle is altering it's positional squareness with the vehicle centre line, then the rear axle will be steering the vehicle in an uncontrolled fashion at EVERY bump in the road.

It sounds like the vehicle need a "woman mechanics look" to find the issue. Females always say they can find things blokes cannot!

Aside from the above suggestions, it's also common for steering rack bushes to wear. You'll need to place the steering under side to side steering load whilst leaving your smart phone camera underneath to watch any prevalent movement. Poly bushes are the go in there. Tie rod ends in steering rack side are a common worn component too. If not one side, the other. Don't just check one side. Use genuine replacement parts there, as generic quickly fail with off-road use. Make sure your steering fluid is clean, as contaminates soon flog out rack seals, as do torn/missing rack end boots, but that's not your problem. Also check under forward/back load your wishbone bushes. Your vehicle's age might be up for them. It could be a combination of many suggestions, if only a bit on each.
