How do you replace lower rear control arms on a Ford Expedition?

Answer 1

Jack up one side at a time,start on driverside first,its the worse side, put a jack stand under frame, one under axle, leave jack under center of rear end, let weight of truck down onto jack stands, jack jack back up alittle for extra safety,take wheel off for extra room. use a strong air impact wrench on nuts in frame, mine were 24 mm, and a 13/16 wrench on bolt head, it just fits. it takes some wiggling to get it on. you may have to knock the bolt back with a hammer, then cut head of bolt off with a 4 1/2 inch electric grinder, or air die grinder, you can torch it, but i ground mine off. push bolt back through the other way. on rear end, break nut loose with breaker bar, then use air wrench on bolt. knock bolt out. when installing new arms, you may have to use a comealong hooked to safety hooks under your bumper to shift rear axle alittle. put front bolt in other way in towards tank. tighten bolts. on pass side, you may have to knock bolts out with hammer and punch, but new arm and bolts should line right up without using comealong on pass side. also, lock tight nuts. hope this helps
