What makes spider gears break?
A common scenario is getting stuck in the mud or snow and free spinning your wheels trying to break free. When this happens, the spider gears can rotate on the cross-pin shaft so quickly that the differential oil is slung away, resulting in metal-on-metal wear.
How do you know if spider gears are bad?
How to Tell If Spider Gears Are Bad
- Listen for “chatter” from the axle while driving. The sound can either be a grinding or popping noise.
- Inspect the inside of the differential for metal shavings. While there will be a fine dust of metal which is common, larger pieces may indicate the spider gears are falling apart.
Can spider gears cause vibration?
“Banging, clicking or clunking” while cornering can be caused by broken cornering gears commonly called “spider gears”, lack of sufficient positraction lubrication, or worn positraction clutches. A steady vibration that increases with the vehicle’s speed can be caused by worn u-joints or an out of balance driveshaft.
What does a spider gear do?
Spider gears are a part of your car’s gear set allowing its rear wheels to turn at different speeds when necessary without affecting the movement of the car as a whole.
Can you replace just the spider gears?
Spider gear replacement requires removal of the existing tires and brakes, differential cover, cross pin bolt (or roll pin), c-clips, axle shafts and more. For setups without positraction it may be possible to “roll” the old spiders gears out in order to install a new set of gears.
What does a bad spider gear sound like?
Banging. When cornering you hear a banging, popping, or crunching sound, it could be from worn or damaged spider gears. Pinion gears with damaged or broken teeth can cause a banging or clicking noise every 2 or 3 feet when increasing or decreasing speeds.
Can bad spider gears cause vibration?
What gear ratio is a Dana 35?
The Dana/Spicer Model 35 is an automotive axle manufactured by Dana Holding Corporation since 1985 when American Motors (AMC) sold its axle tooling equipment to Dana. The axle was originally named an AMC-15 when it was first made in 1962….Available Gear Ratios.
What happens if you have too much backlash in differential?
This distance is application-specific* and is critically important on all differentials because insufficient backlash causes the gears to bind, while excessive backlash causes excessive mechanical wear. Note that both inadequate and excessive backlash can cause varying mechanical noises.
