Here is a list of things to .look for when buying. Rear springs they tend to crack, broken wire in driver door search it up lots of info,cracked rear panel on tailgate, front upper ball joints, heater blend door also.search that up, and smother shifts in tranny. All are simple to.fix except tranny don't let these problems scare.u can use it to ur advantage. The.4.6 v8 will have a little of a grumbling noise at idle if thee not using the correct oil filter.pit it in drive noise goes away your good.
Emphasis on smooth shifts in tranny but I think.you'll b ok.as for servicing tranny I .can't help.u that the one thing I stay away from. I still believe its a great vehicle you will see a lot of comments on the tranny because it is a popular vehicle. Especially when owners r running them into.high miles. Don't Bing up to#$@ta or some other vehicle because your frame will Rot and rust before you hit 200k imo.
