Gen 1 Taco 99' - Frame Creeking

hi all,
my first official thread on here.
i have a 99' Tacoma Single Cab 5spd, 156000 miles, Belltech 4" lowering blocks, Belltech shocks all around and cut springs up front (from previous owner). I have lubricated and rustproofed everything underneath hoping the frame creeking would stop. This only happens at slow speeds and over bumps/driveways mostly.
Does anyone have any idea why my frame creeks?

Thank you all for your input.

 

*Creaks (like my knees)

Much more likely to be suspension bits than frame.

Any rubber bushings, including sway, all suspect. How you lube and what you use to lube matters too.

If the sound is more rear oriented, leaf springs are notorious for noisy. There are remedies, but no use writing those until you confirm.

 

I will continue to lubricate the rear suspension this weekend and report back. Yes, the creaking is from the rear of the truck mostly.
Thank you for your help.

 

Do some searching using the terms 'noisy leaf springs' or 'squeaky leaf springs' and you'll start finding some options.

 

On a 20 year old truck those squeaky noises can be from a dozen different front rubber bushings up front,
Use a jack lifting the front slowly to see if you can track it down

 

ok, thank you for the tip.
