Expedition Truck Gets Fast Axles
The build on our expedition truck is starting to get fast and furious. Several projects are going on at the same time, not the least of which is the upgrade to fast axles. Well, fast might be an exaggeration. Anyway, our goal is to increase the top speed of the truck from about 55MPH to roughly 65MPH. Not fast, but very acceptable in the world of expedition vehicles.
To accomplish this we are removing the ring and pinion gears in the differential and replacing them with a different ratio gear. I was able to source the replacement parts from a destroyed vehicle in South Africa rather than spending the nearly $4000 that Mercedes wants for them new.
The only trick now is getting all of the ancillary parts; IE bearings, seals and bushings. I will have more updates later this week.
