I have a 1983 300D Turbodiesel. Very loud noise comes from rear axles time to time. Does anybody comment on the noise? My mechanic (not a MB mechanic) thinks that I need two rear axles. If I need to replace the axles where can I find information on how to replace them? Thank you.
Yeah but it could be a vacuum problem which is slamming the tranny into low gear. This will make the axles clunk badly. If they are made worse with a fully loaded car or make an awful click click click noise when goiing around a corner then it's the axel(s). If not and it's clunking then the trannny linkage needs to be adjusted.
Huh? There is no seal on the back and if the pinion seal is breached and the fluid is low it'll get VERY VERY hot and will STINK the whole car up reeking of diff fluid - unmistakable.
I'd egt one from the states. I had an axle replaced by Rolf the uber-wrench and she said of all the rebuilders of CVs here only one was any good and the on we got form them failed after a year. Tiger posted link to a company that seems to do little else than rebuild Benz CV's, I'd try them.
Sounds more like a universal joint to me. I had a bad CVJ on one axle on our
300D and it tended to become more quiet once I accelerated and became more noisy when turning a corner. It would come and go as the balls in the CVJ went in and out of place as the torque, speed, etc., changed. I simply removed the axle, found out which CJF was bad and replaced it. Didn't have to replace the entire axle although this might work better for some DIYers than others. You will need snap-ring pliers to remove the retainer. Be sure everything is super clean during assembly and use gobs of grease as well. Incidentally, you need to twist the yoke of the CVJ all the way to one side in order to get all of the balls in place. A bit tricky but IMHO anyone with a little mechanical experience and larger than average testicles can to the job.
