bought a 4*2 hilux about 5 months now
Closer to the 10000k service i notice some squeaking coming from the rear of the van.
informed TTTL about it and they greased or so they say something in the rear.
For about 2 weeks the squeaks were gone an now its back.
any totoya owners have an idea what this is?

you either need to:

1) underwash and spray with shock oil or
2) spray lithium grease on the leaf springs.

could be a bad cross. greasing it would only take away the squeaking for a while.

I have had my share of squeaking from a bad cross (universal joint) so you should check those. You will hear the noise whilst in drive.
