Adding Gear Oil Rear End on 1989 Gmc Surburbon

The 10.5" Corporate 14 Bolt Differential is a heavy duty differential found on many 1973-2013 Chevrolet and GMC trucks and SUVs, every bit well every bit certain versions of the Cadillac Escalade. Additionally, this differential is found on Chevrolet Express and GMC Savanna vans produced from 1973 to current day.^[ane] Debuting in 1973, this differential is a full floating design with a ring gear diameter of ten.5 inches (270 mm). Equally the name implies, this differential has xiv bolts holding on the differential encompass. The ring gear is non held on with xiv bolts, but rather 12. The 14 bolt differential is a pop axle swap selection for Jeep Wrangler owners,^[2] and is referred to as the "corporate" 14 bolt because of the odd nature of GM'southward corporate structure in the 1970s.^[three]

Not to exist confused with the GM 14-bolt 9 and 1/two inch ring gear rear differential which has c clips to retain the axles unlike a gratuitous floating axle that the heavy duty large brother utilizes. The 9 and ane/2 inch is easily identified from the ten and 1/2 inch past looking at the hub. If the hub protrudes through the center of the wheel, that indicates the more desirable x.v and i/2 inch full floating rear axle. The nine and 1/two inch rear end, while durable in its ain correct, is generally regarded every bit less desirable in high torque applications.

          The 9-1/2 c prune rear was in both the Suburban and pickups in both half dozen or 8 lug varieties.   33 spline axles.  and which was in production through 2009 and even available on a trailblazer SS, SAAB 97x. Ssr.        

General specifications [edit]

• 10.5 in (270 mm) diameter ring gear
• Axles are 30 spline axles
• 1.590 in (40.4 mm) bore shank on the pinion
• Gear ratios: 3.21, iii.42, three.73, 4.10, 4.56, 4.88, v.thirteen, and 5.38
• Carrier break: three.21:1 - four.11:1 and iv:56 - v.38
• i.v in (38 mm) axle spline diameter
• 1.34 in (34 mm) axle shaft diameter
• Axles are dissimilar lengths from side to side
• Removable pinion support
• Weight: 550 pounds (250 kg)
• GAWR: 8,600 pounds (3,900 kg) Max.
• Pinion supported with bearings on both sides of the teeth (straddle mount), which minimizes pinion deflection

Design [edit]

The commencement design was produced from 1973 to 1984. The kickoff design remained unchanged until 1986. This design had drums that were held on by the wheel studs and had a smaller diameter pinion bearing than the second design. The 2d design was produced from 1986 to nowadays. I change that occurred in the second design was that on some models the brake drum could exist removed without having to remove the hub and beam shaft. Additionally, the pinion received a larger diameter bearing while the pinion stayed the same bore, which increased the immovability of the pinion. All these beam are full floating.

Brakes [edit]

Virtually of the fourteen bolt differentials produced through model yr 1998 were fitted with drum brakes,^[4] but some vehicles with the 14 bolt were upgraded to disc brakes in 1999. Drum brakes were offered on many full size GM vans for several more years, only by 2003 all vans came with disc brakes.^[v] The first blueprint of this differential had 3 dissimilar bore brake drums. At first the differential was released with drums pocket-sized enough to fit 15 in (380 mm) wheels. Then after a few years a larger drum was standard on the 3⁄four -short-ton (0.68 t) along with the fifty-fifty larger pulsate on the 1-short-ton (0.91 t). This is an surface area of the axle assembly that is commonly converted by the enthusiast to disc brakes for added braking performance and lower cost of maintenance.^[6]

Pinion [edit]

The pinion is supported both in front end of and backside the pinion teeth,^[vii] an arrangement often referred to as "straddle mounting". Straddle mounting greatly reduces pinion deflection under high torque loads, conferring increased longevity and torque chapters. The pinion is also removable from the back likewise making for easier admission.

Re-purposing [edit]

The ten.five" fourteen bolt differential and axle is quite pop with Jeep Wrangler owners who want to upgrade their standard Dana 30, Dana 35, or Dana 44 beam. While the 10.5" 14 bolt axle is heavier than the standard Dana axles offered on the Wrangler, it is much stronger. This increased strength allows Jeep Wrangler owners to mount up to 44" tires without business organization about axle shaft breakage.^[viii] Many Wrangler owners will have up to 2 inches removed from the bottom of the x.five" 14 bolt differential housing to maximize footing clearance.^[9]

Due to the popularity of GM trucks and vans, 10.5" 14 commodities axles are mutual in junkyards. This makes them an choice for any number of vehicle customization projects, buggy builds, and even classic trucks.

xi.5 AAM [edit]

The xi.five AAM xiv bolt rear differential began to replace the 10.5" xiv bolt in many Chevrolet Silverado and GMC Sierra trucks beginning in the 2001 model yr. However, the ten.5" 14 bolt beam continues in product today on GMC Savanna and Chevrolet Express vans. The 11.5" 14 commodities axle is also used in 3rd Generation Dodge Ram 2500 and 3500 trucks. The GM version uses a newspaper gasket and the Ram version uses a re-usable safe gasket. This attribute also makes the Contrivance and GM axles appear very unlike, considering of the unlike embrace used. The GM AAM axle tubes are reduced to smaller bore than the AAM Dodge'south at the spindle from the housing, from 4" to 3.five". Newer GM trucks are congenital to the aforementioned specs as the Dodge axles. GM also opted to have a vibration dampener installed on the yoke, while Dodge opted to place the dampener on the bulldoze shaft. This became the standard axle on all 2500 and 3500 RAM trucks for model year 2014.

Features [edit]

• Increased GAWR: 6,900 pounds (iii,100 kg) Max.
• 1541 alloy axle shafts
• Larger band and pinion than the "xiv commodities" beam. As well as other components.
  • Although pinion is overhung/no support begetting similar the 14 commodities.
  • Selectable locking differential on Ram Ability Wagon (2014 and newer.)

10.five AAM [edit]

2500 3rd Generation Dodge trucks employ a 10.5 AAM in all the V8 equipped trucks. Some early model Diesel and V10 trucks too used this beam. Like the 11.5, this axle also uses a re-usable rubber gasket and looks similar to the 11.five axle. The Ram Power Wagon likewise uses this axle with a locking differential. 2013 was the last model year that RAM 2500 and 3500 trucks were equipped with this axle.
