Topic: toe out after wheeling

[82 HiLux]

so the last 2 times i have taken my truck out wheeling, on the drive home i notice my front tires are screeching like crazy. i get home and measure the distance between the tires on the front and back of the front tires and it tells me i have a whole bunch of toe out, instead of about 1/8" toe in.  its an 82 straight axle with high steer and billet steering arms. 
the last time this happened i fixed my alignment and it was fine again. i went wheeling after that and the same thing happened again. but my tie rod isnt coming out of adjustment, the jam nuts are super tight and havent moved.  im about to go adjust it, yet again. its not right though because its not that its coming out of adjustment, something is getting raped.

has anybody else had this problem? something is getting f-ed up when im beating on it. i dont think the axle housing is bending, i dont beat it THAT hard.  any ideas??

Are your arms tight? And If you are getting toe out the tie rod has to be moving.

i had that happen to me i found out it was a trunnion bearing that went out. mabe check them.

trunion bearings are toast, top ones will probably fall apart and be down inside the knuckle eating the birf

I concur...Trunion bearings being scragly would make the knuckles spread like that while going down the road causing toe out...  \\--o--//

lets say i jacked up my front axle so the tires were off the ground...wouldnt i be able to make the knuckle wiggle on the axle housing by grabbing the tire and shaking it? because everything is still tight. i think this is the most likely cause though, because nothing is bending.  after i set the toe in back to where its supposed to be, it drives normal. but something is really obviously not normal because it shouldnt get thrown out of whack just from hitting some hill climbs.  i havent ever changed the trunion bearings, when i rebuilt my front axle the bearings i got were really crappy and i opted to use the ones that were in there rather than the brand new ones i had. not gonna talk about that though.  time for a front end rebuild, my inner axle seals are blown too and i should probably replace the inner and outter wheel bearings and races. too bad i got laid off like everybody else so i have no money
