the front end in these trucks is pretty beefy.
most problems come from wear, but 78thou miles is nothing, unless maybe you live real close to the salty sea, where rust gets augmented. so, yeah, first put it on jackstands and check for ball joints and bearing adjustment. but also check the tie rods, the idler arm, and the stearing damper, and the swaybar. i had the ball joints on my 85, 266,000 miles, checked by a pro, and they are tiptop, and never been changed. but then, that was a good year for Toy trucks, and i seem to have been lucky with the one i bought.
