Installing floating axles may seem daunting, but it’s a straightforward process when you break it down step by step. Don’t worry, even seasoned mechanics had their first time. The process itself takes about 4 to 6 hours depends on your experience and the tools you have at your disposal. Here’s how you can do it without losing your cool.
First, start by lifting the vehicle and ensuring it’s securely supported with jack stands. Safety first, always! I can’t stress enough how important it is to use quality jack stands; you don’t want your car collapsing on you. Most shops recommend using 4-ton or higher jack stands for added safety. Once your vehicle is securely up, remove the wheels using a high-torque impact wrench. Did you know a good impact wrench can save you at least 30% of the usual manual labor time? Investing in such a tool is a game-changer.
Next, you’ll need to remove the brake calipers and the brake rotors. Store them in a safe spot, as brake rotors can easily get damaged if dropped. On average, brake rotors can cost anywhere from $30 to $75 each, so keeping them out of harm’s way can save you an unexpected trip to your local auto parts store. Once that’s done, you’ll have access to the axle.
You’ll need to disassemble the existing axles. This often involves dealing with the differential cover. Pop the cover off carefully and be ready for gear oil to come out. Many enthusiasts recommend having a drain pan with at least a 5-quart capacity to catch all the oil. This particular gear oil can sometimes be reused if it’s still in good condition, saving you around $20 to $30.
To install the floating axles, first remove the old semi-float axles. The floating axle design dramatically reduces the load on the axle shaft itself and instead transfers the load to the housing. This makes for a much more durable system, particularly important for those who use their vehicles off-road or carry heavy loads. For example, a company like Dynatrac has popularized the use of floating axles for off-road vehicles due to their sheer durability.
Now, you’ll want to slide the new axle shafts into the axle tubes. Be gentle but firm; the new shafts will slide in with a bit of resistance due to the tight tolerances. Companies like Currie Enterprises recommend using a bit of gear oil to lubricate the end of the axle as it goes in. This makes the process smoother and prevents potential damage to the spline ends. Always make sure the axle is fully seated into the differential side gears.
With the axle shafts in place, it’s time to assemble the wheel bearings and retaining plates. These need to be torqued down to specific specifications. For example, many manufacturers recommend torquing these bolts to between 80 and 100 ft-lbs. Don’t guess here; use a quality torque wrench to ensure you get it right. Incorrect torque settings can lead to uneven wear and premature failure, costing you more in the long run.
Once the axles are secured, you can replace the differential cover and seal it with RTV silicone gasket maker. Give the RTV around 15 to 20 minutes to set before adding new gear oil. This setting time ensures a proper seal, preventing leaks that could drain your differential and cause damage. You’ll need around 2 to 3 quarts of new gear oil, depending on your axle specifications. Make sure to consult your vehicle’s manual for the correct type and amount.
Now, reinstall the brake rotors and calipers. Don’t forget to check the condition of your brake pads while you’re at it. A good rule of thumb is to replace the pads if they’re less than 4mm thick. Replacing the pads now can save you from double work later on. On average, brake pads cost around $50 to $100 for a complete set, depending on your vehicle model and brand preference.
Finally, once everything is back together and torqued to spec, lower your vehicle and test drive it to make sure everything functions perfectly. Floating axles offer significant benefits in both durability and load-bearing capabilities, making them an excellent investment. If you ever get stuck or have doubts, plenty of resources like floating axle guides are available online, offering detailed instructions and valuable insights. Don’t hesitate to use them.
