Hey

Got a real bad creaking noise in the rear on take off and under weight. Sounds like the rear leafs or perches creaking but I've sprayed them with oil lube to no avail. Ideas?

Superlift bracket kit with blocks and 3in bl

Thanks

My leaf springs squeek, and then I grease them up, and it stops, but then it comes back. I am already use to it.

Anyone have a way to fix it besides spray lube like WD40 or ZEP45? Can you pull the shackles apart and pack them with grease? I'm pretty sure its the leafs because it creaks only when the leaf pack would stretch or be under load.

Also I have a little bit of the same noise up front but I think its just the lift kit parts creaking. I have all of those torque-checked and all are tight.

Just is getting noiser every week and would like to quiet it down some.

you can get greasable bushings for the springs and shackles

IIRC, WD-40 is a penetrant not a lubricant. It will make it quiet for a little while but it will come back. Spray some lithium grease or some silicone (the aerosol flavor) on them, you might want to bounce the vehicle around a little while you're doing this to promote penetration of the lubricant. Use it on all your bushings (ie. UCAs, LCAs, leaf spring bushings, etc.).

its prolly axle wrap causing the springs to bind up/ make noise

x2. Every moving part that doesn't have a grease fitting gets a spray of heavy duty silicone on my truck.

Maybe try spraying some WD-40 in between some of the individual leafs to help lubricate them and see if that helps. Don't most leaf packs have small flat plastic spacers between each leaf to prevent vibration and excessive noise? Maybe one of those got worn out?
They do, but after 100k some of mine are worn thin or missing.

Ahh yea, that's what I meant :crazy: Thanks for the correction. :)

That's why I got rid of my leaf springs all together! :lazer: :rofljest:

Thanks for the advice! I tried to add some regular grease between some of the leafs but I'm sure that it's the axle wrap causing it. Would full drop leaf springs help? I heard that they rode a lot harder than the factory ones so I'm not sure if I'll do that... maybe a 3" leaf and a 2" block?
