look for an id tag on the axle. if it doesn't have one take the cover off the differential and count the teath on the ring and pinion gears(big circle and small gear biting into it) then use simple division ex. 16 on the pinion and 44 on the ring equals 4.11
NEW ANSWER; He's right about counting teeth on gears, But you need to divide
the # of teeth on pinion gear into the # of teeth on ring gear, and round off #
That will be your gear ratio for sure.
A ring gear of 40 and a pinion gear of 13 is a 3.08 (40/13=3.0769...)
You can waste your time taking the dif cover off or you can do it the old fashion way. The easy way to figure it out is to jack the vehicle up off the ground put the trany in neutral and rotate the tire one full revolution and while doing so count how many revolutions the drive shaft turns. For example if you have a 4.11 rear gear ratio the drive shaft will spin 4.11 times for every single tire rotation.
It is a good idea to mark the back side of the tire where it is closest to the ground with some masking tape. That way you can see when you have made one full revolution as well as putting a mark on the drive shaft and axle housing. Not only is this easier it is alot cheaper than buying new diff lube and a gasket for the axle housing.
You can refer to your user manual to ID the rear end gear ration in 80 Chevy pickup.
It depends on the gear ratio of the rear ends. You can find this out in the glove compartment of your truck. It should tell you there. Hope this helps you out.
The rear gear ratio of a 1989 Chevy Cheyenne truck is between 2.73 and 4.56. This is the number of times the drive shaft rotates in relation to the tires.
Keep it tuned, add an aftermarket air filter such as K&N, change the rear diff gear ratio,
The stock gear ratio for a 1995 Chevy Blazer is 3.73. This provides a good balance of fuel economy and power to the rear wheels.
4:11 gear ratio
If your asking about the gear ratio, Then write the VIN # down and call a Chevy dealer and ask for parts. Then ask the parts man if he'll tell you the gear ratio and that you have the VIN# on you truck. He'll tell you what the gear ratio is from the factory.
Need to remove the rear end plate. Then count the teeth that is on the ring gear ( big gear ) and write it down. Now look up inside of the housing and you will see another smaller gear that runs in the big gear, That will be the pinion gear, count those teeth now. Now take this # and devide it into the first # you wrote down and this will be the gear ratio. You will have to jack it up and take it out of gear, so you can turn the gears to be able to count them.
i believe it would be 3.11
Same as the rear.
If it has stock-type tires, a 3.08 should work good for economy, and a 3.50 for power.
Is a rear end in a 88 4x4 Chevy truck the same as the front in gears of a 93 Chevy 4x4
the rear end is prob 3:42 limited slip rear end
They used a few of them. Open the cover, count the teeth on the big gear ( the ring gear ) next count the teeth on the small gear ( the pinion gear). Divide the big gear by the little gear and that is your ratio.
I have 89 Chevy extended cab pickup 350ci 700r trans i would like to know the rearend gear ratio and if 89 3/4 ton rear would help tow 6500# camper have replaced leafs with 3/4 springs seems original rear geared to high trans gets hot
most common ratio is 373
2.833 is the rear-end gear ratio
The rear end gear ratio on a 1980 Oldsmobile is 3.73, in the overdrive gear. The low gear ratio is 1.43.
It could be any gear ratio. what you need to do is remove the rear end plate and count the teeth on the ring gear, then count the teath on the pinion gear. and divide the pinion teeth # into the ring gear teeth # and that will tell you for sure just round the # off you come up with.
They are all different. try looking in the glove box it might say in there.
To know for sure, You need to remove the big metal plate on the rear end housing and count the # of teeth on the BIG round gear / Ring gear. Then count the teeth on the small round gear / pinion gear that sets deep in the housing and runs on the big gear. Then divide the small # into the high # and that will be you gear ratio.
You'd have to look at the RPO code in the glove compartment to determine this, as there were a couple different options. The gear ratio for the front and rear axle will match.
You have a RPO code in your glove box. I have a 1997 Z71 and my rpo is GX4 and the rear ratio is 3.73 You can use your vin number abd call Chevy or a axle place like Jaspers
