#528 of 2991 jmac..here is TSB on drive shaft.

MAKE SURE YOU GET THE NEWEST ALUMINUM shaft, NOT A STEEL ONE. THEY ARE MADE BY DIFFERENT MANUFACTURERS !!
Driveline - Thump/Clunk Noise
NOISE - "THUMP"/"CLUNK" HEARD ON LIGHT
ACCELERATION FROM A STOP OR WHEN
BRAKING AND COMING TO A STOP - SLIP/STICK
SENSATION AT REAR DRIVESHAFT SLIP - JOINT
SPLINES 4X4 SUPER CAB ONLY
DRIVESHAFT - "THUMP"/"CLUNK" NOISE HEARD
ON LIGHT ACCELERATION FROM A STOP OR
WHEN BRAKING AND COMING TO A STOP - SLIP/STICK SENSATION AT REAR DRIVESHAFT SLIP - JOINT SPLINE - 4X4 SUPER CAB ONLY
This article is being republished in its entirety to update the model year applications for the service parts required.
Some 4X4 Super Cab vehicles may exhibit a low frequency "thump" type noise/vibration on light acceleration from a stop, and/or when
coming to a stop with light to moderate braking. This may be caused by axle wind up during acceleration or deceleration and creating a
stick/slip condition at the rear driveshaft slip-joint splines causing the "thump"/"clunk" sensation.
Replace 3.5" steel driveshaft with 4.0 "aluminum rear driveshaft. This requires installation of a revised fuel tank skid plate. for vehicles built
before 1/15/2001 equipped with the 4X4 Off-Road package. Refer to the following Service Procedure for details.
Reference yellow balance mark on existing steel driveshaft. Using chalk, paint-pen or equivalent, index a mark on the rear axle flange
in-line with yellow mark on driveshaft. This will enable the new driveshaft to be reinstalled in an original balanced state.
Remove existing steel driveshaft from vehicle.
Using the previous reference mark on the axle, align the applicable revised aluminum driveshaft yellow mark to the axle flange mark.
This will assure correct orientation of the new service driveshaft.
Install new service driveshaft and t6rque all eight (8) fasteners to 88-119 Nm (65-87 lb-ft).
Remove fuel tank skid plate for vehicles built before 1/15/2001 equipped with the 4X4 Off-Road package.
Replace with new service Skid Plate (1L5Z-9A147-AA).
Torque fuel tank skid plate fasteners to 34-46 Nm (25-34 lb-ft).
Verify condition has been corrected by accelerating from a stop, and/or with light to moderate braking when coming to a stop.

#529 of 2991 jmac13...one more thought.

MAKE SURE that the shaft is greased properly, and at proper intervals. This is very imortant. Centripetal force can have a nasty habit of flinging lubricant into the boot, OUT of the very mating surfaces that require the lubrication. Then, the splines can get galled, and the whole phenomenon can recur. The new alloy shaft is heliarced to splines that are machined with closer tolerances, and are of a harder steel allow to insure resistance to deformation. DOUBLE CHECK to make sure they were lubed properly IN THE FIRST PLACE !! It is possible some young mechanic simply slapped it in there and did NOT lubricate it to spec. Also, Ford requires the grade of grease required; that is ALSO important !! Regular chassis grease is not used, and may leak out, as it may not take the friction related heat of a spinning, vibrating shaft.

Thanks for the input. So your telling me that the dealer will know acknowledge the Aluminium shaft and install with no problems - thats cool.
One more thing. Sometimes after coming to a stop I notice a low pitched hum, like a high pressure fluid travelling through a hose coming from the engine. I can't find anything on it. Any Ideas?
Sep 18, 2002 (5:16 pm)
I am not acknowledging that your dealer will do ANYTHING. All I am saying is that my dealer, AFTER I took him the printed TSB, finally did acknowledge the problem. Print the TSB out and take it to your dealer. If that gets no results, write to Ford registered mail (return receipt requested) and tell them the problem. You will very likely get support. Ford doesn't need to lose any more customers, as they are already hemorrhaging money like a stuck sow. Good luck...and BTW, my next truck will be a Toyota.
#532 of 2991 Driver side mirror
Sep 26, 2002 (11:12 am)
I've got a 2001 Ranger Edge with power side windows. Yesterday a roommate borrowed it and came back with the driver side mirror almost dangling from its post. There don't appear to be any breaks in the plastic and the glass face is intact. Any suggestions on how to get the housing mounted back properly?

Yea, tell your roomie you are taking it to Ford to get fixed, and he's going to pay for it.
#534 of 2991 stalls intermittantly - wont start- then runs fine
Sep 27, 2002 (8:26 pm)
94 xlt with 4 cyl, 75k miles, recent tune-up - occasionally the check engine light comes on, then goes off with no noticeable running differences. i know that could be anything, but, 2 or 3 times per year, this truck will stall or refuse to restart; it has spark when cranking, seems to want to catch (sneezes a little)- seems like a fuel prob. (like a vapor lock condition on non-fuel injected cars). If i let it sit a while, it will start right up & run fine for another bunch of months!!!
tune up included air & fuel filters, plugs, wires, cap, rotor, fuel additive.
will O2, MAP or airflow sensors do this ? if so, why not more often? (by the way, the check engine light does not happen at the same time as the starting problem)
#535 of 2991 niks...STALLING

Try changing to a new gas cap.

You might also check vacuum lines. I would also say MAP sensor would probably be worth trying too, and the o2 sensor shouldn't do much except cause poor fuel economy.

I have a 1995 Ford Ranger 4cylinder that died on me at a stop light. The truck had been running fine and gave no symptoms prior to shutting down. When I turn the key to pwr I cannot hear the fuel pump at all. It there an easy way to verify pump operation prior to dropping the fuel tank?
