What does a bigger rear differential do?
A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.
When does a rear wheel have a limited slip differential?
If it rotates in the same direction (forward), the rear end has a limited-slip differential. If the other wheel rotates in the reverse direction, then the rear end has an open differential. It is that simple.
How much does it cost to replace rear differential?
The cost of replacing a rear differential depends on the degree of the repairs that need to be done. Just a few parts to replace will cost significantly less than lots of parts to replace. This could run the bill up from the $200-$400 range to $600-$800. Replacing the rear differential entirely costs a whole lot.
What’s the difference between front and rear differential noise?
Only difference between a wheel bearing noise and a rear differential noise would be the fact that the wheel bearing noise will change with wheel speed but usually will not change with load variations (accelerations/decelerations) while the noise from a rear differential will change with wheel speed and load.
How does a Ruff Stuff differential cover work?
Unique dipstick/filler cap design allows differential oil level to be adjusted for customized high driveline angles Constructed from 3/8″ thick plate steel, The Ruff Stuff Specialties fabricated Differential Cover is super stout. The sealing surface is machined perfectly flat, with all seams fully welded inside and out.
How is the size of the rear differential determined?
The size of a rear differential, or rear end, is determined by the diameter of the ring gear inside the differential housing.
What’s the difference between 8 inch and 9 inch differentials?
There’s an easy way to tell an 8-inch apart from a 9-inch. All of the 8-inch case nuts can be accessed with a socket. In contrast, on the 9-inch, two nuts on the bottom at about the 6 and 7 o’clock positions cannot be accessed with a socket and require a wrench.
What kind of differential does a Ford Dana have?
Ford installed a large number of Dana – Spicer differentials both in the front and the rear ends of their pickup trucks. When ordering parts for your Ford Dana rear end it is a critical to have that bill of material number to ensure that you find correct parts the first time.
How can I tell what rear end ratio I have?
One common technique to identify differential ring gear diameters is cover – cover gasket shapes, to help you we have provided a list of possibilities . We have also included link to assist you in determining what rear end you have, as well as a large list or rear end parts.
