    I am going to look at this truck tonight. I did a search, but did not find out much except the oil pans rust out. It has 116,000 miles on it. What else should i be looking for. I have never looked at a Diesel before. Any help would be appreciated.

    Front wheel bearings are a good thing to check as well. some trucks have big problems with wheel bearings and some don't. just hit or miss

    ck the lock out hubs if there moving freely . also does it have either manual 4x4 lever or elec. some of elec are know to freeze up from lack of use . if can get any service record great . one of biggest things esp on PSD is coolant make sure its been flush'd changed . psd are known for calvation problems . if you have an auto trans ck the fuild level and smell it for either a brunt or sweet smell . also ck how the trans shifts . while you have it parked . shift thur all gears there should be no delay at all . ball joints are very common problem on superduty trucks . if i can think of anymore i'll tell ya . i'd also get an oasis report before you do any transaction of cash IMO . hope it helps

    have the ball joints checked as the stock ones are ungreaseable and will fail.

    def check the pan, its like 1,500-2k dollar job depending on where you go to have it fixed, you have to basically pull the motor to change it.

    thank you for the replies. I looked at it tonight, and it had a huge lift, and it was leaking oil, but did not look like it was coming from the pan, almost looked like it was coming from the rear main. For a 99 was in good shape, but i could tell rust had been fixed on the doors already. Looks like i will keep looking. Thanks for the pointers i will keep them in mind i can find another Diesel.

    99.9% of the time on PSD esp 7.3's the rear mains don't leak . the oil leak comes from the HPOP fittings . there a lil o-ring back there that drys out or gets hard as a rock and cause a leak . CAC tubes are another common leak area that can fixed by retrighten them . turbo peds. o rings another common leak area as well as ebv if have one on the turbo housing
