Original Miles?????
my 79 f150 has 68000 miles on odom i was sceptical,took to an upolstry shop and the old dude there said that it has the original interior (said the seats are original stitching never been touched)said if it wasnt original miles the seat would be worn out and you can tell the diff between an coverd seat compared to original,if these are original miles then why do i have a klunk noise when i go in reverse isnt 68000 miles a little to soon fo u-joints or rear problems.posted a questin about the rear noise everyone is betting on u-joints but i cant find a honest mechanic who wont rob me for the rear

My '77 has 40,200 miles on it and the rear pinion seal is shot. Is that normal for that many miles? Time takes its toll on some things, as much, if not more than miles do. There are many things that could have happened. It could have a part that was defective from the factory and it just wore out now. You could have a seal in the U-joint dry rot, fall apart, and allow the grease out and dirt in. The U-joint could have been assembled with not enough grease and it took this many miles to fail. A weld could have failed and your drive shaft is broke not the U-joints. You could have a loose pinion yoke. The drive shaft usually makes more of a "clinking" noise though. Like hitting a piece of metal with a hammer. A "clunk" is usually deeper, and is usually an internal noise like the tranny or rear end. The fluid changes the pitch of the sound. Good luck.
