TR6 Clunking After selecting gear and letting clutch out a mechanical clunking can be heard and felt mid section. Clunking also occurs if slowing up in high gear. Have changed both rear drive shafts and universal joints. Diff seems ok. Still clunking! Any suggestions would be appreciated. Phil

The bearings in the gear box are gone. When in 4th gear the input and output shafts turn at the same rate 1 to 1 ratio. In all other gears the shafts are turning a different rates and the clunking is a slight meshing of the gears. When the clutch is depressed there is no power (load) on the input shaft.

The driver side outer cv joint has worn ,you will find if you put all the weight of the car on the drivers side it will clunk when driven in a circle then try it oppisite lock it shouldnt make that much noise.the bearings have worn in the outer cv joint easy job to replace.
hope this helps.

clutch not fully disengaging
air in the system /problem master cylinder or clutch cable failing

Sounds like a drive shaft but you would hear a clonking noise so it could be the clutch gone ,if i was their with it infront of me i could soon tell you the problem but from afar ? ask a local mechanic to have a look for you as this is one of them questions its impossible to give a correct answer

ask a local mechanic to have a look ,no idea from this description it could be anything broke loose or whatever

may be the gears in the rear end or check your motor mounts, ive had the noise and it was motor mounts

its possible your clutch cable got stretched out. if you are lucky, your car came with an adjustable cable stock, and the slack can be picked up, it not, the cables arent too expensive, and with a little work, you could install it yourself. but its not the most fun job.

have your friend sit in the car and push the clutch pedal, and measure how far the little arm connected to the tranny (that will move up and down when the clutch pedal is pushed and let out). it should move almost an inch at least.(generally) some cars if the clutch is worn enough dont require it to move quite as far.

your clutch might be worn, was any of the oil you changed somewhat metallic? Ive heard to check for a worn clutch: pull the car up to a tree, put a tire or some kind of cushion between the car and the tree put your car in its highest gear, give it gas and very slowly let your clutch out, if the clutch is good the car will shut down immediately.

Sounds like youi may have a few serious problems going on to have that kind of back lash occuring at higher speeds. I have experiance with low spped clunks on Bronkos and your type of vech being a car dealer. One you might try for low speed clunk on take off and braking at stop likts just completeing a stop? Pull the drive shaft and lubricate the splin - two check your leaf springs for weakness and wore bushings - take a look at your shocks - three u bolts holding springs to rear axle housing may be letting the axle housing actually dip or tweak or all those thing in combination - now you may have some serious slop in the pig - transfer case may be causing that clunk - as far as high spped clunk and activity you have a serous problem and you just might drop the transferr case have an accident fliping over..............Mike South Bend Indiana don't just keep driving and making problem worst...........
