I had an 86 toy 4x4. 1st year with ifs, and I think with the the 22 re motor. Remember hauling my bikes through nj when it began making a knocking noise....next thing the crank broke. Toyota engineers looked at the crankshaft saying it failed from a metallurgical issue. Only had 40k somethihg on the odo. Toyota gave me a 2wd loaner for the week with unlimited miles, plus a remanufactured engine at no cost.
