Leaf springs issues

I checked it but thanks for the idea, what I'm doing now help a lot, turning up the radio

 

Thats what I do as well. My leaf springs are absolutely smoked..

 

They are made by Dobinsons. They are a pretty reputable brand of aftermarket Toyota suspensions from Australia.

 

Any recommendation for leaf springs stock height replacement

 

Not sure if this helps, but my 2017 leaf springs squeaked quite a bit when the truck was fairly new. I asked the dealer on one of the "free" oil changes and they put in this small black discs ~1" or so between the springs. I have not heard a squeak in a few years. Maybe there is a part number someone can dig up for these "discs?"

 

All come with those discs, are those specials?? And I know for sure at least one source of noise comes from passenger front bushing

 

If you're on factory leafs and they are squeaking from the bushings, that's pretty rare. You can replace the bushings.

If you have poly bushings in the leaf pack, you can get greasable bolts, but they require modification to work right. You need to drill out the poly bushing sleeve to let the grease flow, and you need to change the washer/nut on the end to something actually automotive grade.

If the noise is from "between" the leafs, they are probably dirty. Jack the truck up (not from the axle) and let the leafs/axle droop as much as possible. Take the wheel off. Power wash, let dry, use a degrease such as purple power, spray all over them, power wash again, let dry. Use a can of fluid film to treat the leafs and between the leafs. Be careful, this is kinda messy, use a cardboard shield as to not spray everywhere. This will quiet them down for a few months.

 

Thanks for the input, I have stock springs, regarding the greasable bolts I'm a bit skeptical about their strengths, can I use those with stock bushings?? I have no clue what poly bushings are

 

No, you would use greasable bolts with poly bushings. Poly bushings require grease to keep quiet.
