View Full Version : New to forum, mechanical question
12-22-2007, 10:42 AM
Hello....I have a question pertaining to my 2000 Ranger 3.0 4x4. I hope i'm in the right place....When I pull off from a stop there is a "clunk" in the drivetrain somewhere, like there's some slack someplace. Just a mild to moderate bump. A "mechanic" told me that it's normal in this 4WD truck...Does he know what he's talking about? Thanks in advance for any advice!

Welcome to TRS.
I have always had that on my truck and never really noticed it. You might try the 4x4 forum. I know its been posted on here a few times. If you try searching you might be able to find some info.

i *think* that problem is normally because of the slip joint in the drive shaft. the fix is a special grease from ford to regrease the splines. im pretty sure there was a tsb about it at one time with a part number for ford's fix grease. hopefully somebody else can fill in the details.

Thanks, that is encouraging news. I'll try searching to see if I can get more info. Again, many thanks!

I found this thread in the transmission forum......sounds like my problem. Thanks to all for the advice and Happy Holidays!
FORD: 1998-2005 Ranger
This article supersedes TSB 03-26-2 to update the vehicle model years and service procedure.
Some Ranger 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, creating a stick/slip condition at the rear driveshaft slip yoke splines.
A new type of grease is available which will greatly reduce the sticking/binding in the slip yoke during acceleration and deceleration. To service, apply the new grease to the rear driveshaft slip yoke splines. Refer to the following Service Procedure.
NOTE: OTHER DRIVELINE NOISE CONDITIONS WILL NOT BE CORRECTED WITH THIS PROCEDURE. REFER TO THE APPROPRIATE RANGER WORKSHOP MANUAL FOR DIAGNOSIS AND REPAIR OF ENGAGEMENT CLUNK, TIP-IN/OUT CLUNK OR CLUTCH ENGAGEMENT CLUNK CONDITIONS.
Index (mark) the rear driveshaft to the rear pinion flange and the front of the driveshaft to the transfer case flange.
Remove the rear driveshaft.
SLIP YOKE DISASSEMBLY
CAUTION: DO NOT, UNDER ANY CIRCUMSTANCE, CLAMP THE DRIVESHAFT IN THE JAWS OF A VISE OR SIMILAR HOLDING FIXTURE. DENTING OR A FRACTURE CAN RESULT, CAUSING DRIVESHAFT FAILURE DURING VEHICLE OPERATION.
Place the driveshaft on a suitable workbench. Do not damage the tube.
Mark the driveshaft and slip yoke on both sides of the boot. Mark the location of the clamp crimps so the new clamps can be installed in the same location (Figure 1).
Figure 1 - Article 04-23-7
Cut and discard the slip yoke boot clamps.
Remove the slip yoke from the driveshaft.
Thoroughly clean the boot making sure to remove all of the old grease and dirt. Inspect the boot for damage.
Inspect the lubricant on the driveshaft splines and in the driveshaft slip yoke for contamination. If contaminated, inspect the driveshaft splines and slip yoke for wear.
Using a stiff NON-METALLIC brush and a suitable solvent, thoroughly clean all the old grease out of the splines on the slip yoke and the driveshaft.
Use compressed air to completely dry both spline areas.
Install the slip yoke boot on the driveshaft (small opening end first).
Install and crimp the small slip yoke boot clamp using a keystone clamp installer (SST 211-002).
Pull the boot toward the driveshaft to expose the splines. Completely coat all slip yoke and driveshaft spline surfaces with the grease supplied in the kit.
Position the large slip yoke boot clamp on the boot (DO NOT CRIMP).
Align the index marks and install the slip yoke on the driveshaft.
Set boot free length as follows:
Remove any excess grease from the slip yoke boot and driveshaft slip yoke surfaces.
Position the slip yoke boot in the slip yoke boot groove.
Set the boot length to 3" (76 mm) by sliding the slip yoke. Measure between the inner side of the clamps as shown in (Figure 2).
Bleed the air from the slip yoke boot using a screwdriver as shown in (Figure 2).
Crimp the large slip yoke boot clamp using SST 211-002.
Figure 2 - Article 04-23-7
Align the driveshaft front index mark with the mark on the transfer case flange and install the driveshaft. Torque the bolts to 82 lb-ft (111 N-m).
Align driveshaft rear flange index mark with the mark on the pinion flange and install the driveshaft. Torque the bolts to 83 lb-ft (112 N-m).

Disregard that part. That will work temporarily but it won't fix your problem for good.

Since I put pigger tires on it's less noticable. That's my suggestion

Thanks for all the input. Sounds like this is a pretty common problem. Is it something that needs to be addressed or should I just learn to live with it?

I had the same sound / problem. Used regular axle grease on the splines. Worked great, and haven't had a problem (or noise from the drive shaft) since.
Be absolutely sure to index the shaft and the slip joint before you work on it. If done incorrectly, it will cause imbalance and vibration from the drive shaft, and wear the drive shaft out prematurely.

Thanks so much everyone. What a great resource! Hope I can return the favor...

I have an 88 4x4 Supercab Ranger, I had the noise when putting in reverse and then drive, it ended up being the middle bad u joint and also a bad carrier bearing to hold the 2 piece drive shaft in line. It now is quiet and no noise.
