Getrag broken bolts

[jdross440]

On my 92 W250 I noticed oil dripping on ground under my Getrag transmission. I crawled under and saw it was coming out from between the transmission case and bearing support/transfer case adapter/mount. After getting a good light and looking I saw 3 of the bolts had missing heads. 2 on top and one on passenger side. Also the remaining bolts were loose about 1 round. The truck has about 350K miles. I figure the bolts loosened causing the transfer case weight bouncing up and down popped the heads off the top and passenger side bolts. If I hadn't noticed the oil leak it could have lost most of the fluid and burned the transmission up. Now to get the bolts out. Looks like I will have to pull the transfer case, unbolt the mount bolts and slide the adapter back to get to the bolts as not enough room to get to them with it together.

That's a though brake, lucky you caught it in time, from what I can see the bolts you have say 8.8 on the head, that's the metric equivalent to a standard grade 5, I would replace all the bolts with hard bolts, marked with 10.9 on the head
