Front wheels toe in while in 4WD
Hello...... Guys I have a 1987 Toyota truck 4wd. 22r engine 5 speed tranny. 33" tires and balljoint spacers in front blocks in rear. All stock suspension settings. Okay anyways I just went about 3 days ago and had a new front end alignment think it would cure my problem. When the shop done the alignment they replaced my idlerarm. Other then that they said everything else was fine. K now to my problem....
When I lock my truck in 4wd the front tires seem to toe in making it a little difficult to handle. It only does it when I give my truck a lot of fuel or if I'm on a hard pull. I pulled a friends SUV up a little gravel hill last night and it done it really bad making my truck bounce left to right.
Has anyone else had this kinda problem. Winter is here and snow will be next here in WV. I'd like to have it figured out before I have to be driving in snow. Thanks a lot.

Did the shop suggest anything else to replace on the front end? Does the it do the jerking while driving in a strait line? When I have my locked into 4x4, I get "grabbing" while turning.

No the shop inspected everything and that was the only thing that was bad. If I in a straight line and goose the throttle the front suspension raises up and the front wheels turn slightly tward each other causing my truck to bounce left to right were the wheels are fighting each other.

How's your steering stabilizer? Mostly, it just sounds like an exaggerated version of normal ifs operation. As the front end rises, the camber goes negative and the toe goes in. It's probably made worse by the 33's.
Are they 12.5" wide? I've experienced similar with my Runner, but they're only 10.5" wide 33's, so that could be why mine doesn't do it as bad as yours.

Want to get rid of it? Run tiny tires, don't use 4wd or get a solid axle.

Think of it like this...what if the steering linkage were to suddenly disappear. What's going to happen when you hit the throttle and the front wheels begin to turn forward? Since there's nothing in between the steering knuckles(as in the steering linkage), as the wheels roll/pull forward, they will start to rotate inward towards each other in the front by pivotting of the steering knuckles. This would cause an instantaneous and drastic toe in condition to exist. And if you were then to put it into reverse and apply throttle, as the front wheels began to roll/pull backwards(pivotting towards each other in the rear), it would cause a toe out condition to occur.
If that isn't making much sense, just know this. When the front wheels are under power, pulling forward, they want to turn in towards each other in the front(toe in, or toe out under power in reverse). This is because they are connected to the vehicle on pivots(the steering knuckles). Basically, because they are steerable. And even good steering components can, and do, have a little play. Which will allow it to happen...
Anyway...it's more of a FWD thing, than a 4WD or IFS thing. Think about it......

Thinking through it a little more, you shouldn't have a problem with this in the snow...at least not on the streets. I'd hope you're not hammering down(when you have the problem) unless you're snow wheeling or something like that.

My tires are 33/12.50-r15 and they are mounted on 12" wide wheels as well so yeah I do have a really wide tire. I drive my truck as it is my only vehicle besides my wife's XL7. My everyday driving is not affected by this. Although like I said before I am only really affected when I'm under a heavy pull. Me an my family are constantly out wheeling and I have never really had a problem with my steering. I geuss it was just more of curiousity then a real problem. But thanks for all the info
