Now just put your torque wrench on the large nut in the center of the adapter and take a reading of the torque before the axle begins rotating. A picture of using a dial indicator was shown early in this article and is easy to read as long as you remember your readings are in thousandths. At this point, the differential case should be completely empty. If you look closely at the side gear near the circular window on the left, you can see a portion of the cone surface. My opinion is to avoid this altogether and stick with the latest recommended order of plates G-R-F-R-R-F-R-F-S.
The remaining parts installed on the axle are the wheel-end bearings and seals. One of the most common reasons to replace a wimpy stock axle assembly is that it could only handle the torque from the stock engine. Some kits, for example, cater to the budget-conscious while others focus more on performance than on price. Axle Reassembly The wheel ends can be tackled next. Do not forget the spherical pin-ion washers that go between the pinion gears and the differential case. For instance, a vehicle with 30-inch tires, 4. Tire noise is usually most prominent around 60 to 80 mph.
The destructive method is to cut the cage with a set of side cutters and remove the cage and rollers. This is because of torque multiplication: As torque increases, the speed of rotation decreases. Perhaps others who actually have used those needle bearing devices could post their experience and for myself I would like to know, when using those devices, how the clearances are adjusted for proper end play and gear mesh etc. The ultimate installation, tuning and troubleshooting guide for the Holley modular style carburetor. Ring Gear Bolts General Motors used bolts with different sizes and thread pitches for the ring gear. And finding the most suitable kit for your needs is essential to ensuring that you'll get what you need without overspending.
Usually prying is required to remove the differential, but you need to be careful here and not pry on the ring gear teeth. The first step is to drain the axle fluid. Covers must more than just the differential repairs. Both axles are quite similar and actually use the same bearings, and there-fore, one tool works for both. Tighten the bearing caps to the proper torque.
These are not direct bolt-up parts. I found the above problem, plus the inner bearings were worn and pitted. Wet down rags with solvent and push them down the axle tubes and retrieve them from the center section of the axle. Not only does this make the gear weaker, it also limits the top speed of the vehicle. In most cases, when rebuilding a differential back to stock you can reuse the original pinion shim without having to measure for pinion depth. Remove the differential cover making sure to have a drain pan underneath to catch the old gear oil.
Carefully examine the axle, propshaft, brake lines, and even the suspension mounting points. The axle shaft is the inner bearing race, so with the axles removed, you can see the rollers. Notice that the pinion seal keeps the bearing in place. A must have along with your rebuild kit and manual. A very good mechanic friend of mine who shall remain nameless, used to use those a lot when they first came out but then said he doesn't use them any more and he never elaborated as to why and I would like to know the whole story myself. In addition, this book provides a comprehensive identification chart to ensure readers properly identify the model and specifics of the 9-inch differential.
This will make it easier to drop the assembly into the differential case. If you look it over you can see that the mesh of the ring gear and pinion, the clearances, etc. I highly recommend this, another great book from CarTech. The easiest method to measure the pack is to lightly clamp the pack with a C-style clamp and measure the overall thickness with a set of calipers or a micrometer. The steel reaction plates do not require this step.
Many front-wheel-drive carriers also use left-hand threads. And if the covers are made out of composites, they will crack. This rebuild was performed on a 2006 F150 Crew Cab 4×4 with a 9. Another important reason is to help distribute the torque to the wheels from a high-performance engine and transmission combination. Now stop one wheel from rotating such as jacking only one tire off the ground , remove the other wheel, and put the adapter over the lug studs.
You have to find the balance between top speed and quickness for your application. The new differential is far quieter than our worn out 3. This does allow for more friction surfaces and additional torque capacity in theory. The typical application for this axle is the V-6 Mustang. .
