Replacement Axles for 1984 300 SD ??
Thinking of buying replacement axles for my '84 300 SD. Can't find anyplace that sells them. Saw some threads that state '84 380 SE axles fit. Some sellers show 26 1/16" length or 24 13/16" length. Anybody know which one fits?
Thanks.

The Axle length is measured with the Axle compressed.
If it is only an issue with the boots it is possible to replace the Boots. Then there is also that famous rebuilder in Col. CVJ (I think those are the initials). Note I believe they would also rebuild your own if you are willing to wait.

If you have the original 3.07 differential (wider) and homokinetic axles, the replacement axle is shorter.
I've converted mine to a 2.47 differential (narrow) and installed annular axles, which are longer. The advantage to this is lower rpm's at cruising speed (quieter), slightly better fuel mileage, and ease of repair (replaceable cv joints/boots). Some have used the 2.88 differential (used on the 85) because of better off-the-line performance. However, they are more rare. Also, I'm not sure about the width of the 2.88 differential. I gleaned a lot of information from here: http://www.peachparts.com/shopforum/diesel-discussion/249673-2-47-1-2-88-1-axle-116-120-a.html

If you like cheap. A pair of used still with good boots from a wreck. Drain the cv lubricant and replace it. Install them on the other sides of your car in comparison to what they were on the wreck. Should outlast your car.
Very few cars will appear in wrecking yards because the rear axles failed. The issue is to find a pair with still good boots. Also there is little doubt the same axles where used on the gas cars. Swapping the axles gives you a new wear surface. Original ones probably fail primarily because of lubrication issues. The manufacture designed a good lubricating system for these axles. He just never considered they might be in service for thirty to forty years. Even adding a couple of ounces of thick oil with the axles on the car is still a slight maintenance attempt. If yours have no current issues other than old boots. There will be people that can reboot and inject the right amount of lubricant out there. Just make sure to reverse the axles when replacing them. Using the thick oil as they were designed to use as a lubricant is best. |
