Often loose steering and leaking is
caused by worn out knuckles. Toyota used an enclosed CV joint in
the front axle. This kit is commonly referred to as a knuckle
rebuild kit. This kit contains all the bearing and seals to
rebuild your knuckles on BOTH sides. There are several reasons you
may need to rebuild your knuckles. Often the inner seal begins to
leak which cause the differential oil to mix with the knuckle
grease. This makes a soupy mess and often leaks on the back side
of the tire. Another reason the knuckles are loose is the knuckle
bearings (sometimes referred to as the king pin beaings). Bigger
tires, miles, steering wear them out. They can be checked by
jacking the vehicle and rocking the tire with your hand on the 12 and 6
o'clock position if it moves excessively they need rebuild. As a
general rule, if your knuckles have not been rebuilt, they need to
be.
