Editing Rearend identification

{{youcanedit}} ==Ford== Ford used a vast array of rear ends over the years. Below are some of the more common rear ends. ===Removable carrier=== [[Image:9inch.jpg|thumb|left|200px|Removable carrier, rear view.]]<br style="clear:both"/> ===8-inch=== ====ID==== An easy way to tell the difference between the 8-inch and the 9-inch Ford differential is that on an 8-inch, a socket will fit on the lower nuts seen in this picture. Since the pinion centerline is lower on a 9-inch, a wrench is needed to gain clearance. [[Image:9inchrear.jpg|thumb|300px|left|8 inch Ford differential details]]<br style="clear:both"/> ===9-inch=== One of the strongest Ford rear end was the 9". Still one of the best rearends to modify or use in stock form to handle big horsepower. [[Image:DSC02404.JPG|thumb|left|400px|9 inch Ford rearend]]<br style="clear:both"/> ===9 3/8-inch=== Removable carrier. Found in some Lincoln, Mercury and Thunderbird. ==Non-removable carrier== ===8.8-inch=== [[Image:88rearend.jpg|thumb|left|400px|8.8 rear end in a F150 4X4]]<br style="clear:both"/> ===8.7-inch=== Non-removable carrier. Found in Granada, Monarch 1977 to 1978. [[Image:87rear.jpg|thumb|left|300px|8.7 inch Ford rear end]]<br style="clear:both"/> ===7.75-inch=== Non-removable carrier. Found in Fairlane. ===7.5-inch=== Non-removable carrier. Found in light duty applications such as six cylinder Falcon, Fairlane and 170 cid Maverick (Mavericks powered by 200 cid, 250 cid and 302 cid engines had the 8-inch differential). ===7.25-inch=== Non-removable carrier. Found in Falcon, Econoline, Fairlane, Comet. ===7-inch=== Non-removable carrier. Found in Falcon. ===6.75-inch=== Non-removable carrier. Found in some Pintos and Mustang II. ===Columbia 2-speed rear end=== More of an overdrive unit than an actual rear end. Included in the Ford section since it was offered as an option on '30's to '40's Fords. ==General Motors== ===12 bolt=== ===10 bolt=== [[Image:10bolt.jpg|thumb|left|300px|10 bolt 8.5 inch GM corporate rear end]]<br style="clear:both"/> The corporate 10 bolt 8.5 inch rear end uses a 2-series for 2.41 and 2.56 ratios and a 3-series carrier for 2.73 and lower (higher numerically) ratios. ====10 bolt ID==== If you don't have the codes on hand to identify if a 10 bolt rear end is an 8.5" or not, you can measure the distance between the very bottom bolt for the cover and the next adjacent bolt (either right of left), it will be 3-3/4" for a 8.5" and 3-1/4" for a 7.5". The ring gear of the corporate 10 bolt is secured by 7/16" '''LH''' bolts- 10 of them. The ring gear is (as mentioned) 8.5" diameter and the pinion shaft diameter is the same as the 12 bolt at 1.625". '''Carrier casting numbers''' 3 series (2.73:1- up): '''410408N''' 2 series (2.56:1- down):'''410409N''' ==Mopar== ===9.25=== ===8.75=== ===8.25=== ==Others== ===DANA=== ====70==== ====60==== ====44==== ====41==== ====35==== ====30==== ====28==== ====27==== ====25==== ==Related resources== [http://www.crankshaftcoalition.com/wiki/Ford_9-inch_rear_ends Ford 9 inch rearends] [[Category:Rearend]] [[Category:Identification and decoding]]
