Symptoms
Oil on the transmission-mounted handbrake drum, a handbrake that won't hold, or drips from the transfer flanges.
The fix, step by step
- Old Patrols commonly blow their transfer-case front or rear output seals, according to SNLC, and if the rear one goes, it destroys the handbrake.
- Drop the driveshaft, remove the flange nut and flange, and replace the seal.
- He found Nissan's OEM seals were double-lipped and much better than the single-lip aftermarket seals in his truck.
- If the handbrake drum or band lining is oil-soaked, clean or reline it at the same time.
