Mercedes 123 126 Chassis H.D. Hex Socket for Motor Mount Removal

Removing the front rubber engine mounts requires getting under the car and going up inside a hole in the subframe to remove the main bolt. And it can be a bear! I don't know who they hired to tighten these at the factory but he must have been a brute. These hex bolts are usually in very tight and you will need a heavy, strong and tight fitting 8 mm hex socket. Only 1/2 inch drive will do. You don't want to break off the tip nor do you want to deal with a rounded out hex under way up inside that channel... Talk about a big wrench dance...

This tool works on 116 123 126 DIESEL 240D, 300CD, 300D, 300SD, 300SDL, 300TD, and 126 gas V8  380SE, 380SEC, 380SEL, 420SEL, 500SEC, 500SEL, 560SEC, 560SEL 1977 to 1991.

This is how you access those bolts.  Yes that is correct - way up inside that hole...
