no flaming in here
the truck, if it is a 85, is a solid axle front end. It is easy enough to tell. but the seven inch lift is a give away as well.
But back to the issue on hand. The running on, or dieseling is most likely carbon build up on the pistons and valves.
Especially after running the cheapest gas you can find with low octane and with bigger tires on a high mileage 22r.
since the truck is a straight drive
has big tires
high mileage
low octane fuel
poor upkeep
suggestions: 93 octane with octane booster. and some good fuel system cleaner through it for a few tankfuls
it might be a good idea to take it to a certified mechanic and let him check the whole thing over for you.
But please at the least take it to the car wash, that is if you can find one that will let you wash the mud off,
and pressure wash that sucker down really good.
you need to have the third members checked for water and mud if it was submerged for a long time
(long enough to cool down is all it takes)
Plus depending on how deep it was submerged you may need to check
the transmission, clutch pressure plate and throw out bearing and transfer case as well.
but most certainly take the rear brake drums off and wash out the
excess mud from around your brake parts and axle seals.
Wash around the pinion seals front and rear.
Take the front tires off and wash all around the front knuckles and knuckle wiper seals.
wash out around the slave cylinder on your clutch system. the seals around your steering box and especially around all the seals on the front of your engine. A/C, starter, fan clutch, water pump, main crank seal alternator bearings
mud is fun but it as bad for everything on your truck.
Grease all your available grease fittings.
at the ujoints of both drive shafts, steering j arm joints, and any other grease fittings you see.
this is just some friendly advice to save you huge bucks down the road.
pinion seals, axle seals, gears, and transmission seals, transmissions, clutches and stuff are all exspensive to replace when you don't have the experience to
do the job yourself.
one other thing take your garden hose and a sprinkler and just set the sprinkler under your truck and move it around
occasionally to loosen most of the dried mud. do this for several hours to soak the mud. then wash it with a pressure washer of some sort
