These trucks are brutally hard on everything in the front end
And like mentioned above, KDP, possibly trans (especially if the engine has been modded).
If its 4wd you will definitely want to make sure that its working, the CAD in the front axle is pretty failure prone after this many years. Though its not a hugely expensive fix, its just something to work down the price if hes asking too much.
How much is the truck going for?$?$
