TobyJH Member Date registered: Jan 2016 Location: Calgary Vehicle(s): 1988 300 GD Posts: 5 | Gap in short Propeller Shaft - Is this normal? Looking for Vibration Hi, We are trying to locate a new vibration that developed very suddenly. It seems to be rpm related, and not speed related. In slow speeds it is a lot lower and not as bad. It gets very bad had high speeds. Seems to be a very low frequency, rapid vibration. The photo below is the short shaft that goes from the back of the transmission to the transfer case. It seems to have a strange gap on the transmission side. Is this normal? If not, what could cause this gap? Could this short shaft be the cause of the vibration? HISTORY Also to note, we took out the Propeller Shaft from the transfer case to the front axle. This was causing a vibration, and as soon as we took it out, that shake left, and the G-Wagon drove completely smoothly, with no vibrations. The shop told us this transfer case to front axle shaft was bent and needed to be replaced. Then the clutch slave cylinder blew up, we replaced that, and suddenly this vibration developed in a very short time. (probably co-incidence with the slave cylinder). Is this sudden, new vibration related to us removing the transfer case to front axel shaft? Can we drive the vehicle with this shaft removed? Or, is this causing the gap to form in this short shaft? In the video, see the play also in the shaft, by the gap, how do we fix this?? Video of gap: https://youtu.be/ptKf7umWwxo Thanks so much for your help. 1988 300 GD, 5 cyl, 5 speed 460.333, om617.95 engine (IMG_3768WEB.jpg) Attachments ---------------- IMG_3768WEB.jpg (299KB - 1 downloads) | ||

Looking for Vibration Did you engage the transfer case to drive the front axle even though it was removed? I recall that it must be engaged to secure proper internal lubrication with the front shaft removed. | ||

Looking for Vibration Not normal!! Something major has failed, and the Getrag is infamous for failures of that bearing. That is most certainly the source of your vibrations. This has been discussed here some time back, and a custom part was made to fix and prevent the problem from happening again. Also, do NOT, repeat NOT, drive the vehicle in "S" (2WD street) with the front drive shaft removed. Without that front drive shaft you MUST drive either in "SA" (4WD street) or "GA" (4WD off-road). The Transfer Case requires the gearing in the TC for the front axle to turn the pump in order to lubricate the TC. | ||

Looking for Vibration Seen this before. The nut holding the output flange to the transmission shaft is loose. Remove the shaft and tighten the nut. It has a shoulder that you bend to lock it in place. Dutch is refering to the input bearing at the other end of the transmission. Before that one goes it will be noisy with transmission in neutral and clutch out. Warren | ||

Looking for Vibration Hi Folks, Yes, sure enough, when I took the shaft off, the nut fell right out! I will post more photos. Replaced the nut with a new one, ran the tranny up by itself, and everything felt good and solid, with just the flange attached. Lubed the drive shafts all, reinstalled the short one, and installed a new one to the front box. She runs perfectly!! Never felt it so smooth and quiet! It sounds like a brand new G-Wagon!!! I wanted to top up the tranny fluid, the service manual says ATF Type A, can you folks please confirm that? Or, is there a better type? Also, what is the easiest way to access to top up the Tranny fluid?? (A real newbie question, sorry http://www.pointedthree.com/disc/images/emoticons/smile.gif ) Thanks again so much everyone! | ||

Perhaps, more accurately, about a couple tablespoons or so of fluid came out when I took the flange off. Is this Tranny fluid? Or, Gear Oil? How do I top this up? Thanks again, | ||

Good luck finding ATF Type A. Dexron is an acceptable substitute. | ||

I checked the manuals, and couldn't find those plugs. Only the drain one. I guess the manuals aren't written for a dummy like me! I'm learning though! | ||

I'm learning though! the manual shows the transmission only from the left side the fill plug is on the right and you are right, Mercedes considers the oil change as so trivial, that it is not covered in the repair manual. However, it is shown in the service manual (you have that one). both drain plug and fill plug require the big allen wrench you have in your onboard tool kit (only used for fluid openings in axle, transfer case, engine and transmission) | ||
