How do I lubricate the rear chassis?

[Derek]

When I go over bumps such as the bump to pull into my driveway the rear chassis has a noticeable squeak to it when it flexes. My last 4th Gen did the same thing so I know it's somewhat normal for the age. What should I lubricate to get rid of the noise? Bushings? Something connected to the rear axle? And what should I use to lubricate these particular areas of the 4Runner? I apologize if this has been covered in another thread. I tried searching but I'm not sure what to search for.

If you go up and down with the air suspension do you ear it ? I've had the famous driveshaft issue with my '03 and found the probleme by cycling the air suspension ! Anyhow are you shure that it's not the front balljoint squeeking ?

How many miles on you're truck ?

I don't have air suspension but it's definitely the rear. I also hear it on hard acceleration from a stop when the rear suspension compresses. I'm pretty sure it is part of the rear suspension/chassis making the noise. Guess I need to have someone climb in the rear and see if i can locate the noise.

Hit the bottom contact point of both rear springs with *lots* of WD40 and see if it goes away ... for a while.

Best to narrow down where the noise is coming from, lots of places it could be.

Also, seriously no Astro Glide jokes for the "How do I lubricate the rear chassis" thread? I'm ashamed of this forum!
