Gear ratio rearend


The pining noise you are hearing is detonation in the engine and comes from incorrect air/fuel ratio making the engine run too lean, It is spontaneous combustion occurring before spark and tends to drive the piston back down the bore. It is detrimental to the engine and should be rectified asap. Run fault codes and look for sensor problems. Vin numbers are unlikely to show the gear ratio of the rear end as there are 4 ratios for each model of car. Jack up on side of the rear . count the number of turns the pinion does for each revolution of the wheel . Divide that by 2 ( side gears in diff carrier multiply by 2 when driving one wheel)and you will get the ratio. So 10 revolutions of the tire gives 35.5. revolutions at the pinion equals to 17.5 or a ratio of 1.75: 1 ratio

Rear end went out... Need help finding the Ratio to it...


There is supposed to be a code on the front of the left axel tube. It may have lots of paint covering it.
You can also pull the cover, count the teeth and do the math. (the ring gear will also have numbers on it).
What I have done, but others say they have no luck, is call the dealer with your VIN. The VIN leads to a data base with everything that was on the build sheet. The build sheet would have the gear ratio.
Some have said the dealer could not help them. The delaer has helped me before so I know first hand it can be done. And your truck is not too old either.

What is the rear end ratio for 2005 Jeep Liberty limited edition 4wd


You will need to locate the tag on the rear end cover and find out the gear ratio, if theres no tag then you will need the manufactors date on the door, for example 04/05, and also if it got abs, there are three types,4.10 or 3.55 or 3.73. the best way is the tag or pull cover and count the teeth on ring gear and pinion gear and divide the two to get the ratio. goodday, also try to call the dealer parts dept and give them the vin # and they may be able to tell you the type rear end you have,

1989 s10 blazer rear differential small gears worn, teeth ok.


The gear ratio will be stamped on the outside of the ring gear itself.You will need to change the ring and pinion gear. The side and spider gears should not have to be changed unless there is something wrong with them.Changing a rear end gear set takes a fair bit of knowledge and special tools.Make sure you have what you need before trying it. Good Luck.

Need to know what model will fit a 1997 rear end because make noise and they say i need anew one


96 to 2001 should fit but you have to find the gear ratio, if you look on the glove box door when you flip it down there will be a bunch of codes. the gear ratio code will be GU6 or something like that. Definitely start with a "G".

I have a 1991 dodge dakota that blew out the rear end, where can i find the gear ratio for the new rear end that i need?


I will assume you are missing your id tag. You will need to remove the rear cover and count the teeth. If you have never opened a drive axle I will warn you it will most certainly stink.

Now to figure the gear ratio:

The best way is to count the teeth on the ring gear and divide by the number of teeth on the pinion gear. Or you can count the number of turns of the pinion it takes to get one full turn of the ring gear.


For example, if we divide a ring gear with 41 teeth by a pinion gear with 10 teeth we find that the gear ratio is 4.10:1 (41/10 = 4.10).

Want to change gears in rear end for posi traction in a 98 gmc25000 is this possible?


It is possible, you just have to know what gear ratio you have in your Sierra. I had issues with my son's rear differential and did the Salvage Yard and picked one up for $250.00 with less then 45,000 miles. Remember new cars end up at Salvage Yards also.

Here are the Pro code for the rear ends to your Sierra and you can match one up at a Salvage Yard.
GQ1 -- AXLE REAR, STD RATIO
GT4 -- AXLE REAR, 3.73 RATIO
GT5 -- AXLE REAR, 4.10 RATIO
GU4 -- AXLE REAR, 3.08 RATIO
GU5 -- AXLE REAR, 3.23 RATIO
GU6 -- AXLE REAR, 3.42 RATIO
G80 -- AXLE REAR, LIMITED SLIP (POSI TRACTION)

HC4 -- AXLE REAR, 4.56 RATIO

Open Your glove box and look inside it. Should be a list of codes on the bottom.
Example: GU6 G80 According to that, you'll have a 3.42 posi

Good luck and keep me posted and call around Salvage Yards, there prices will differ from one to the next salvage yard and don't ask them for a posi rear end. The cost will you more, just search all the SUV's and look at the pro codes in the glove box. Hunt, most awd system SUV will have the G80 rear end.

Good luck and keep me posted.

Rear gear ratio for 93 toyota 4x4 pickup 5 speed.


The C/Tr: C refers to the colour of the vehicle Tr refers to the interior colour A/TM is your transmission type. None of those numbers identify the rear end ratio.

What you need to do: Since you have to replace the rear end, yank it out. Examine the ring & pinion gears on the differential carrier. Mark on each a starting point, and count the teeth on both the ring & pinion gears. Now, after you have both totals of teeth, divide the # of teeth on the pinion by the number of teeth on the ring gear. Example: 12 teeth on the pinion, 46 teeth on the ring
12/46 = 3.83 ratio
