**Introducing the definitive Cruiser Patch beginner's guide to the 100 Series Toyota Land Cruiser!**

curated by Patch Agan

Driveline "clunk"

Front diff bushings (most noticeable shifting from D to R or upon acceleration if extremely worn out)
Greasing all six (6x) zerk fittings on front and rear driveshafts (most noticeable when accelerating from a stop)
CV axles and drive flanges (excessive wear can cause a "clunk" when shifting from D to R and vice versa)

Heater tees

Factory service manual recommends 90,000 mile replacement
OEM plastic tees are prone to crack. Some prefer upgrading to OEM brass tees or deleting the rear heater entirely (deletes heater tees).
OEM constant tension clamps are highly recommended over worm-drive clamps as heat cycles and environmental temperature changes can cause leaks.
