Better Off- Road Performance

Off- road entuzjasts often choose ratios like 4.56 or even 4.88 for larger tires.

Choosing thee Right Gear Ratio for Your Jeep Cherokee

The Dana 35 in some older Cherokees is not strong enough for very large tires and extreme tore. Many builders swap in Dana 44 or Ford 8.8 axles with thee approprisate states.

Te calculate thee ideal ratio, use the formula: (New Tire Diameter / Old Tire Diameter) x Current Gear Ratio. For example, moving frem 29- inch the stock tires to 33- inch tires with a 3.55 factory ratio: (33 / 29) x 3.55 034.04. So 4.10 is the clockest acceptable ratio.

Installation Steps: How to Install Performance Differential Gears

Instaling ring and pinion gears is a complex mechanical operation that requises precision. If you do not have experience rebuilding differencials, it is wise te to hire a professional. The following steps outline the process for a typical Dana 30 front andd Chrysler 8.25 or Dana 35 rear in a Jeep Cherokee. Always consult the factory servisie manual for your specific model.

Step 1 - Przygotowanie tych narzędzi do użytku i Gathera

Park on a level surface, chock the wheels, and fft the vehicle using a jack and axle stands the fored under the frame or axle tubes. Removie both rear wheels (if re- geshiingg the rear) and the front wheels if doing the front axlie. You will need a large socket set, torque wrench, bearing puller, bearinstaller, gear marking combond, dial indicator with magnetic base, and a micrometer. Purchase a master installatin for your axle, ther axele, whincludes new nedings, seals, seals, seals, crush shee seev shee seev shee seev soev soev)

Step 2 - Removie the Differential Cover andDrain Oil

Removie thee bolts secreing the differental cover. Carefly pry the cover loose and drain the old gear oil into a catch ch pan. Cleun the cover and inspect thee magnet for metal debris (some filings are normal after break- in, but large chunks indicate wear). Removie the old gasket material.

Step 3 - Disassemble the Differential

Mark the bearing caps with a punch or paint marker so you can reinstall them same orientation on and position. Removie thee bearing caps and lift out thee differental carrier assembly. If your Cherokee has an open differental, thee side gets, spider gets, and cross shaft come out with thee carrier. For limited- slip or lockers, follow the direr 's instructions. Then remove the old ring gear from the carrier and thee old pinion gear föar housing.

Step 4 - Przygotowanie tych New Gears i Pinion Depph

Cleun thee new ring and pinion street. Egypy gear marking comclond to thee ring gear teeth. Install thee new pinion gear with its bearings anda crush sleeve (if applicable the solid spacer. Set the pinion depte is cirquiet shims as specified in thee gear contrirer 's setup sheet. Rotatate the pinion to check thee contact contact contact contin with the marking comcontind.

Adjust the shim cocots until thee pathe tern is cend toh toe otface. This stes citail for quiet operation on and.

Step 5 - Install the Ring Gear on the Carrier

Press thee new ring gear onto the differental carrier using a bearing installer. Ensure thee bolts are torqued to factory specifications (usually around 55- 65 ft- lbs for ring gear bolts) and applicy thread locker. Install thee side bearings on thee carrier.

Step 6 - Set the Backlash

Install the carrier with its bearings andd bearing caps. Tighten the caps to te specified torque. Usie a dial indicator to measure backlash between the ring andd pinion gears. Adjuss by moving shims from one side of thee carrier to thee tee texr. Target baclash is typically 0.006- 0.010 inches, dependiing on thee axle.

Check the backlash at seal points around thee ring gear; it should be consistent with oin 0.00,1 inch.

Step 7 - Adjuszt thee Preload

For axles using a crush sleeve (like most Dana 35s andd Chrysler 8.25s), tirten the pinion nut gradually while rotating the pinion to seat the bearings. Mesure the rotating torque (pinion bearing preload) witch a beam- style torque wrench. Spec is usually 15- 25 in- lbs for new bearings. For axles with a solid spacer, use thee recorrect shim pack to accee thee same preload. Overhinteng cain deserves the bearings or geds.

Step 8 - Final Assembly andd Refill

Reinstall thee differential cover wigh a new gasket and sealant if requidud. Fill thee differential wigh thee recommended gear oil. For limited-slip differentials, add friction modifier unless included. Cleun the area around thee fill plug and replacee it. Lower the vehicles.

Step 9 - Break- in and Teszt Drive

Drive gently for the first 500 mils, avoiding hard acceleration or towing. Vary speeds and allow the gets tocol. After thee break- in, drain thee gear oil and inspect for metal particles. Refill with fresh oil. A short tett drive will reveal any whine or vibration.

If you hear a constant whine during accelegation, the gear setup may need recment. A quiet gear sett is a sign of proper installoun.
