Ring gear bolts are secured with thread locker, which prevents them from loosening because of the many heat cycles experienced throughout their life. The first step is to suspend the chassis and let the rear extend freely under the car. This was back in 2004. A significant amount of force is required to get it moving, but once it does, the carrier slides right out. Take this opportunity to mark each side. Reattach the u-joint strap bolts and tighten with the air wrench and socket. Step 3: Remove Axle Shafts Special Tool Several methods can be used to extract the C-clip from the carrier housing.
A bad wheel bearing will send a lot of metal shavings through the gear oil. Properly align the bracket under the axle ends and torque down the bolts with a socket and ratchet. I chose to keep the six-bolt pattern. I will need a new pin-ion and ring when I reassemble this axle. Street vehicles, however, must strike a fine balance between the two, and that means factoring in several key components such as intended use, transmission type and gearing, and tires. All axle work is done on site.
As far as I know, that case comes fully assembled except for the ring gear and the side bearings. Many front-wheel-drive carriers also use left-hand threads. In this case, follow this procedure: Four nuts on the end of the axle tubes hold the drum brake backing plates to the housing and bolt-in axles. Bearing shoulder-to-ring gear surface is 0. If not repaired, a bad bearing can seize, causing an unsafe driving condition. The number of teeth is stamped on each gear.
Although some enthusiasts own media blasting equipment, many do not own the other cleaning equipment. You need to ensure the brake lines are correctly routed so they do not contact the exhaust or any moving parts. Varying Speed: Many axle issues become evident when you quickly accelerate and decelerate using the throttle. Also check the pinion yoke with the same test, after unbolting the U-joint. It is weak and not suitable for performance applications. Pinion Removal At this point, the pinion gear is exposed. Next, rotate the driveshaft and count the number of complete rotations until the tire has made one full revolution.
Please call for customer service and availability at 1-800-886-2815. Built from the 1970s through today the 8. Master Overhaul Kits Lifting your or Chevy Blazer? Step 11: Remove Carrier Shims Carefully remove, tag, and store the shims. Once you break the tension on the pinion nut, you should be able to remove it easily. Inspect the gears as soon as you open the box. If the pin sticks, you can use a hammer and brass punch to drive out the center pin. The end result is a better traction, more power though the engine does spin a bit faster at speed because of the lower gears and all around better drivability.
Illustrated in the image to the left are the parts that are replaced during our factory rebuild process including: ring and pinion set plus a master bearing overhaul kit that includes pinion bearing, pinion seal, carrier bearings, shim kit plus an internal kit for open differential that includes spider and side gears plus thrust washers and cross shaft. Use a screwdriver or scraper to gently pry the cover from the housing. Put the transmission in neutral. Finding the ratio is simple. I got the truck used so I'm assuming the previous owner was not too nice to it as I drove it like a grandma, most of the time. Push the axles in as far as they will go. At the end of its life cycle, the fluid is very dark.
. This can also be a sign that the gears are worn or out of mesh, so any type of howling noise should be inspected immediately. Hand install the C-Clip over each axle shaft end and then use a socket and ratchet to install the differential center pin. Place a drain pan under the center section, and once the cover has been removed, allow the fluid to drain. When things get more serious, the rebuilds get more intense. Step 1: Remove Axle Shafts To remove the axles, the C-clips have to come out. Pull back the boot on the bracket and remove the retaining clip; then the fitting can be removed from the bracket.
The previously installed front discs conversion retained the six-bolt pattern as well. If it spins in the opposite direction, it is an open carrier. Use a carbide burr or sanding roll with a die grinder to open it up just enough so that it slips on and off the new pinion gear easily. Torque the retainer bolts to 150 ft. Place the jack under the center of the rear end chunk to catch the rear end when the last bolt is removed. Then use thread lube and thread the rest of the bolts into the ring gear.
For a gear to achieve more mechanical advantage numerically higher ratio , the pinion gear has to become smaller. This means that the car accelerates more quickly, but with less top-end speed. This Tech Tip is From the Full Book,. This is the proper centering as shown on the ring gear. Aftermarket Carriers Although most aftermarket carriers provide their own details, they tend to follow these guidelines: 2-Series: Gear ratio 2. The red high temperature silicone can be found at most all auto parts stores.
