A few weeks ago my Corolla’s clutch MC failed quite spectacularly, and I had to drive my 48 year old truck to the parts store for a replacement part. It never rains but it pours of course. On the way to the parts store the truck started making a squeaking noise, repetitive, which I guessed to be due to some dryness developing in the driveshaft u-joints. Once the Corolla was back on the road, next I lubed the truck’s driveshaft. Here’s the problem: The lubing instructions for the truck say to lube the rear driveshaft in 5 places, but I could only find 4 places. It’s a two-piece arrangement, splined in-between. One u-joint at the rear differential end, and two u-joints (a poor-man’s CV configuration) at the transfer case end. The four lube points I found were:
- Spline joint zerk fitting
- Rear u-joint zerk fitting
- Most forward u-joint zerk fitting
- Next to the most forward u-joint zerk fitting
Any ideas for the 5th place needing lube?
