CAUSES - NOISY IN DRIVE
| Cause | Correction |
|---|---|
| Inspect for the proper transaxle and gear oil levels prior to performing system diagnosis. Refer to TRANSFER CASE FLUID REPLACEMENT . | |
| Water or contamination within the lubricant Water or contamination within the lubricant, causing excessive torque converter clutch slip rate, may create a grind, growl, or moan in the rear differential or torque tube under light or steady load conditions. |
Replace the lubricant and flush the transfer case of the contaminated fluid. Refer to Internal Components Cleaning and Inspection. |
| Loose propeller shaft mounting bolts | Tighten the bolts, as required. Refer to FASTENER TIGHTENING SPECIFICATIONS - PROPELLER SHAFT . |
| Worn propeller shaft constant velocity joints | Replace propeller shaft assembly. Refer to PROPELLER SHAFT REPLACEMENT . |
| Worn axle shaft constant velocity joints | Replace the constant velocity joints, as required. |
| Loose rear axle torque tube bracket or a worn bracket bushing | Tighten the bracket bolts or replace the bracket, as required. |
| Worn bearing in the rear differential torque tube assembly | Replace the torque tube assembly. |
| Torque tube dampener loose or missing A moan or exhaust leak type noise at higher engine speeds, approximately 2,000-2,500 RPM, may indicate a loose or missing dampener. |
Tighten the dampener retaining bolt or replace the torque tube assembly, as required. |
| Incorrect gear oil in the transfer case | Replace the gear oil. Refer to SEALERS, ADHESIVES, AND LUBRICANTS . |
| Bearing noise within the transfer case A grinding or roar type noise will increase or decrease relative to the vehicle speed. |
|
| Gear set whine noise within the transfer case Whine type noises will increase or decrease relative to the vehicle speed. |
