Gentlemen... I decided to replace the front disks on the shaggin wagin, ordered the new ones from Rusty, and just for fun, since I hadn't done it in a while, read the manual. Do you really have to replace the "self locking hex socket bolts" that say "one time use only"? When I did the job on my old 240D (RIP), I don't think I put in new bolts. In any case, they are not listed on Rusty's web site, which tells me it's not a high volume item.
OBTW...Since switching to Mobil1, I'm up to 26MPG on my last fillup. Admittedly, the fact that the A/C is temporarily dead may have added 1 or 2, but I'm impressed. My daily commute is now 30 miles each way, all freeway, with less than 1/2 mile from the house/office to the on/off ramp. Royce Engler 1985 300TD Turbo 285K
