Oil method: Unscrew it from the transmission and work it(loosen bendable retainers) back up and out the engine compartment. Careful not to kink it!! Then oil patiently and freely letting gravity push it through the cable/cover. A little compressd air may help get th oil to where it needs to go quicker. 89 Truck's been quiet for 8-10 years now and 91 4runner lasted about 4 yrs. It's about due for another lube job. May try synthetic oil this time. Good luck
