I've got a '93 4x4 with the same problem. I plan on getting it lubed as soon as I get a freaking sunny day, I'll let you know if it helps me out. Thanks for all the info.

 

I have a 2001 xlt 4x4. i bought it new and started to notice the common thump when i would stop and then go agian. well i took my truck to the dealer a year after and told them about it and they said they could do nothing about it. so a year later it was getting worse and i took it back and they replaced my drive shaft with a new 4" aluminum one and the prooblem was gone.....

 

Tried to link to the info for doing this,but links are dead.Can one of you send me this info or a place I can find it?Got an appt with the Ford house Mon.,but someone mentioned a $600 bill and I'd like to avoid that if possible.Thanks in advance.

Hi scampi, welcome to FTE!

Don't know why the links don't work for you...they are still valid.

In any case, I emailed you and attached a copy of the PDF file that you are looking for.

Good luck!

 

Thanks,Rockledge.Knew someone would come through.

 

I had the same thump in my 96 Mazda B4000 ExCab. I decided today to drop the driveshaft and check the lube status in the slip yoke. There wasn't enough grease in it to lube your eyeglass hinges. After I reassembled with Valvoline synthetic grease, the problem disappeared. I had been dealing with this for about 3 years, and fixed it in an hour.

 

I have a '99, 2.5, std cab, 5-speed, 2wd. I noticed the postings all seem to be 4x4's, though. The symptoms sound EXACTLY what my truck has been doing everyday since I bought it. It has 63k, and I've never removed the driveline. Does this problem apply to the driveline on my 2wd truck? Just wanted to double check before I start wrenching. Any help would be greatly appreciated.

Thanks,
Andy

 

Not to make you all think I bought it new and it did it then- it had 47k miles on it when I bought it.

 

I have a 96 Ext.Cab that was doing the same. It has the two piece rear driveshaft. Come to find out it was the Carrier Bearing that was bad causing the problem for me.

Can I have a copy of that PM also? My truck does the same thing and the dealer told me it was normal.
Thanks,

Hello all! I have a 97 B2300 5sp extended cab 4x2, and I have the same problem with the thump/clunk that you are you talking about. I would like to grease my yoke too if that will fix my problem. How do I go about doing that? Thank you!

 

Could someone here get me the complete TSB for number 03-4-8? That appears to be the TSB for this problem on the 2001 model Rangers.

Thanks!

 

This is the earlier one.

ISSUE:
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.

ACTION:
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.

SERVICE PROCEDURE
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 torque all eight (8) fasteners to 88-119 N-m (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 N-m (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.
