rear end trouble please help
 

Just when i thought i was done spending money on my lovely 300e then comes another headache

Its started about a week ago everytime i take a right turn I hear this " clack clack clack clack clack " sound coming from the back ,at first it was only doing it when i take a right turn but now it also does it when I am taking off from a full stop then the noise away now i dont know if it is my rear end or the axles, maybe you guys came across this b4 so let me know what it is please took me about a week to post this cause i know it would lead to a few bucks out of my pocket :mad:

Could be several things
 

I would guess it's a universal on an axle but that's only a guess. I hope you have buddied up with a good tech! You may need him on this one!

Sounds like 1/2 shaft time. Do a search on here for 1/2 shaft and read the response. It is my opinion that this is one of the easier diy'er type of jobs although the parts can be pretty pricy.

Axles

If changing the rear axles is anything similar to a W123('81 240D),
it shouldn't take you more than 2.5hrs.
The most difficult part is jacking up the car and removing the wheel.
Put the car on jack-stands; drain the 3rd member; take off the wheel.
You'll find a single bolt in the center of the brake hub; remove it.
Pull the back cover on the differential; you'll find a "circ-clip"on the axle in question; slip a piece of thin wire through the hole in it( if you drop it, you can fish it out); use a needle nose and pull it out.
Grab both ends of the axle and push to the center.
The axle will fall to the ground.
Put a little anti-seize on the splines of the replacement; pick it up and expand it into position.
Put the single bolt back in the brake hub. and snap the circ-clip back into the groove of the axle.
Replace the rear cover(put a thin film of RTV on the mating surfaces) back on and re-fill the differential.
Put wheel back on and jack-down the car.
I have the "HAYNES" manual, and they give a blow-by-blow description.
Good luck. Regards, John F. ('81 240D & '85 500SEC)

thanks a lot guys for replying to my post i have one more question
when u guys say 1/2 shaft r u refering to the rear axles I never own a rear wheel drive b4 I have always owned front wheel drive and the sound that i get is similar to when you have the front axles go bad on a front wheel drive car but this one is louder on the benz thanks guys
