I'm going to come back to this issue in a few weeks or so.
I have more sensitive issues to fix first.
Bouncy side mirrors.
Slight clunk at stop'n'go.
Oil leak.
Sloppy steering.
I love having a used vehicle again.
Fun projects!
Yo Eddie,
Check trans and engine mounts.
Check for a bad/loose engine mount by having helper put it in Drive, foot on brake, then rev up engine. With the hood up you can see if the engine "lifts up" too much (bad or loose mount). Do the test in fwd and reverse gears.
U joints, esp at front of rear driveshaft. "

Rear Driveshaft Slip Shaft needs greasing.

Driveshaft, Rear, One-Piece Removal;
This is how FORD describes it;
"Raise vehicle and install safety stands.
NOTE: On four-wheel drive vehicles equipped with a slip between center driveshaft, disconnect the driveshaft (4602) at the transfer case during removal.
To maintain driveline balance, if the yellow alignment marks are not visible,
mark the relationship of the driveshaft flange yoke (4866) and the rear axle companion flange so they may be reinstalled in their original positions.
Circular rear axle companion flange:
Remove the bolts retaining the driveshaft flange yoke to the rear axle companion flange and disconnect the driveshaft from the rear axle (4001).
Lower the driveshaft and slide the driveshaft rearward off the transmission output shaft.
Install an appropriate plug in the extension housing (7A039) to prevent fluid loss.
Installation:
Lubricate the slip yoke spline with Premium Long-Life Grease XG-1-C or -K or equivalent meeting Ford specification ESA-M1C75-B.
Remove the tool from the extension housing. Inspect extension housing seal for damage. Replace if necessary.
Install the driveshaft slip yoke (4841) on the transmission (transfer case for BRONCO output shaft. Do not allow the driveshaft slip yoke to bottom on the output transmission shaft with excessive force.
NOTE: When installing a new driveshaft, align the factory-made yellow paint mark at the rear of the driveshaft tube with the factory-made yellow paint mark on the outside diameter of the rear axle companion flange. If paint marks are not visible and vibration exists after installation, refer to Section 05-00.
Install the driveshaft so that the index marks made before removal are aligned or the yellow mark (if visible) on the driveshaft tube (light side) is in line with the yellow mark on the rear axle companion flange high side runout. This prevents vibration that occurs when the balance of the shaft and runout of the axle companion flange become additive instead of neutralizing. If a vibration exists, the driveshaft should be disconnected from the rear axle, rotated 180 degrees and reinstalled.
Remove stands and lower vehicle.
Road test vehicle.
Driveshaft Removed
Cut the driveshaft slip yoke boot clamps (4K227) with sidecutters. Remove and discard the clamps
Separate the driveshaft slip yoke (4841) from the splined stub shaft on the driveshaft.
Remove the slip yoke boot. Inspect the slip yoke boot for rips or holes and replace if required.
If, during inspection, the driveshaft and coupling shaft boot is found to be cracked or split, the grease should be checked for contamination. Check the lubricant by rubbing between two fingers. Any gritty feeling indicates a contaminated driveshaft slip yoke and stub shaft. If driveshaft (4602) is operating satisfactorily and the grease does not appear to be contaminated, add grease as described in the assembly portion of this procedure and replace the slip yoke boot. If the grease appears contaminated, disassemble the driveshaft, clean and inspect the stub shaft and driveshaft slip yoke for wear. If splines are excessively worn, replace driveshaft.
If required, remove and replace the U-joints.
Assembly
Install the slip yoke boot with the small diameter side facing the splined stub shaft on the stub shaft. Push the slip yoke boot as far as it will travel on the stub shaft.
Install a small driveshaft slip yoke boot clamp and crimp the clamp using Keystone Clamp Pliers T63P-9171-A.
Compress the slip yoke boot and coat the stub shaft splines with Premium Long-Life Grease XG-1-C or -K or equivalent meeting Ford specification ESA-M1C75-B.
Fill the slip yoke boot with approximately 10 grams of Premium Long-Life Grease XG-1-C or -K or equivalent meeting Ford specification ESA-M1C75-B.
Slide the large driveshaft slip yoke boot clamp onto the barrel of the driveshaft slip yoke.
Align the blind splines on the splined stub shaft and in the driveshaft slip yoke. Push the driveshaft slip yoke onto the stub shaft.
Remove all excess grease from the slip yoke boot and driveshaft slip yoke surfaces. Position the slip yoke boot over the driveshaft slip yoke boot groove.
Move the driveshaft slip yoke in or out in order to obtain the distance of 10 inches between stud shaft weld to the centerline of the driveshaft slip yoke U-joint
Before installing the new large slip yoke boot clamp, make sure that any air pressure which may have built up in the slip yoke boot is relieved. Carefully insert a screwdriver between the slip yoke boot and the driveshaft slip yoke and allow the trapped air to escape ("burp") from the slip yoke boot. THE AIR MUST BE RELEASED ONLY AFTER THE DRIVESHAFT IS SET AT THE SPECIFIED LENGTH
Position the new large driveshaft slip yoke boot clamp over the slip yoke boot and groove in the driveshaft slip yoke. Crimp the driveshaft slip yoke boot clamp with Keystone Clamp Pliers T63P-9171-A
