remove the rear cover all the bolts except the top 1 just loosen that 1. Put a bucket under the rear diff and open the diff cover and drain out the fluid. clean and reseal the diff. remove the plug on the front of the diff and fill with the correct diff fluid until it is filled up to the hole and replace the plug, clean up and check for leaks. No leake = job is complete.

Inspect the fuel filter, remove it, dump the fuel that is inside of it onto a white paper towel to check for dirt and then see how easy it is to blow through it with your breath. It should blow through it pretty easy. Also try a different map sensor.......my .02 cents worth....Mike

89octane is a good start for the fuel,,,,for the oil,,,Use 10w40 motorcycle oil,,,Valvoline makes moto oil,,,,yes there is a diff,,,moto oil give your clutch disk the reqired friction that they need,,,regular auto oil will work but i dont recomend it.

Make sure the differential and auto box are not short of fluids. Many ABS systems take a sensor reading on the differential. If there is evidence that the pinion oil seal has been leaking (diff wet with oil and permanent oil drip at bottom) then it is very likely that the diff is in need of replenishment. The heavy shifts are probably unrelated and are due to low transmission fluid: should be able to refill via the gear fluid dip stick tube

hi if it is an automatic you need to use dexron2 for transmision, if it is a manual you need 10w30 and for the diff 80w90 for the rear hope this helped

theres 3 things ur emisans fail on 1 spark plugs 2 air filters need changing 3fuil filter so yes a full service should do it change ur oil fuil filter air filter oil filter and oil

sound's like your front diff is seized :( could be wrong but id check your front diff fluid for level, color and any metal shaving's as they will be a good start. hope this helped.

cold climate 5W-30W, hot-moderate climate or long commutes at high speeds 10W-30W, these engines are designed for light oils,(very tight clearances) heavy oil's can starve the main and rod bearings of start up lubrication..

I am a Ford tech and the diff doesn't need to be serviced (new lube) unless it is torn down or it has a leak, however it is my opinion that under heavy usage such as towing it should be serviced at around 60,000.
