I have a 1988 Ford Bronco II 4x4 and am trying to remove the front drive-shaft. My Haynes repair manual is no help as to what bolts to take off the shaft. It also seems that no Standard or Metric wrench fits any of the nuts quite right. I have to remove the drive-shaft so I can continue with the clutch removal and am currently stuck. Any help would be much appreciated.

Remove oil pan, making sure to drain oil first. Remove oil pump attaching bolts. Lift off oil pump and withdraw oil pump drive shaft.
Prime the new oil pump by filling either the inlet or outlet port with engine oil. Rotate the pump shaft to distribute oil within the pump body. Insert oil pump drive shaft into block dwith the pointed end facing inward. The pointed end is closest to the pressed-on flange. Place oil pump into position with a new gasket and install attaching screws. Tighten the screws to 15-22 foot pounds of tourque. Clean and install the oil pump inlet tube and screen assembly with a new gasket. Tighten the bolts, then replace the oil pan.
Clean of any debris and replace gasket. Fit the oil pan bolts and tighten in two steps. Start from the rear/left hand side and tighten first, then tighten the bolt in the front/right side. Alternate from rear to front, working from back to front and front to back.
your output seal on the tranny or input seal on your transfer case is bad. you have to pull your transfer case to tell. this is a pretty straight forward job. block wheels. put transfer case in neutral. drop front and rear drive lines.diconnect transfer case shift linkage. there is a short commponent connecting the trans to the transfer case. the bolt on either end face each other. remove the bolts to the transmission. the transfer case is heavier than it looks, i suggest getting help. pull back on the transfer case until it will drop down. it will pull out a bit because of the trans output shaft. replace what will probibly turn out to be the tranny output shaft seal and reassemble in reverse order.
Check the oil level in your transmission, I take it that it's a standard so your going to have to do it by removing the fill plug and felling for fluid. If it's low then you are losing transmission fluid though the front input shaft bearing and seal. Check the hydraulic clutch fluid, see if your losing some fluid there too, You may have a small leak bell housing.
Good luck and keep me posted.
The sound is not coming from the glove compartment, it is coming from the panel behind the drivers seat, that's where the relays and computer are located. The relays click and apply power to a transfer case motor. The motor attempts to turn a shaft that engages the front drive shaft. When the computer thinks the shaft has NOT turned it tries again. It will try three times then quit, figuring the shaft has not turned.
Get someone to crawl under the vehicle and engage the 4WD (just turn on the ignition- do not start the engine) See if they can hear the motor attempt to turn the shaft, it will make a clicking sound. If not the connections or the motor may be bad.
I have found the most probable cause is the relays on the control board. If you are technically adept -- you can remove the small side panel from behind the drivers seat and remove the control board. (remove the power plugs first) Clean the relay contacts and bend them a little to give them more 'wipe' to keep them clean longer. Put it back in and turn on the ignition. Then push the RESET button on the side of the board. Try the in / out 4WD a couple of times. If it doesn't work turn off the ignition, turn it back on and push the reset button again.
