Squeaking AAL...Seeking Permanent Solution

Yes I know this is an old topic....anyway, I installed HS AAL and the squeaking is unbearable. Sounds like a hoopty! I'm looking for a product to provide a permanent solution. So now on to why is it squeaking? I didn't have any squeaking when I had a block lift. I thought by replacing the block with an AAL that would be an "upgrade", more like a pain in the ass! Can I assume it's the aftermarket leafs and not the factory leafs? I have to assume its between the bottom factory and the top aftermarket leaf since the factory leafs didn't squeak prior to the AAL. It sounds like its right in the middle, between the U bolts. I've tried white lithium grease, no dice. Any help or product links is appreciated!

 

The factory pads are known for squeaking, spread them apart and insert some grease/silaglyde on them.

 

Thanks but why didn't they factory pads squeak prior to the AAL?

 

Disturbed? Maybe they did but you are more tuned in?

Hard to say but its a starting point I suggest for all 3rd gens.

 

The block from before put different pressure on the shims than the AAL does. I’m not aware of any permanent solutions to prevent the squeak on the stock shims. Just use a pry bar and separate the leafs slightly and grease a few times a year. Takes maybe 15 minutes.

 

Thanks, no need to loosen u bolts to spread leafs?

 

Also, I forgot to re-install these when i installed the AAL. Are they necessary and where do they get installed?

 

Did you take apart the AAL's and apply grease between the leafs before installing like the HS instructions say? Mine don't squeak at all.

 

Nope. The ends of the leafs are all you are worried about. I blast them with the pressure washer. Then spray some silicone grease on them.

 

I sprayed some white lithium grease but I don't think I applied enough and not evenly. Any particular grease and how did you apply it? Did you brush it on or just smear it with nitrile gloves?

 

I used heavy duty/bearing grease and just used a nitrile glove and smeared it on. I did not put it on thick, just a nice coating. I think marine grease would be good also, but not lithium. Cover the top side of each leaf and assemble.

 

I use motorcycle chain lube lol. Oddly enough, my squeaks haven't came back going on 2 summers now...but they used to bad! (HS AAL)

 

^^^^^ This. i have HS AAL and used a liberal layer of lithium grease between each upon installation - 2 years later and no noise.

 

Leaf-liners, is a permanent solution. Grease, you will have keep reapplying.

 

What product did you go with? Link please. Thanks!

 

I think this would work perfectly...thoughts?

$21 Leaf Spring Liner with Lip, 2", Black

Leaf Spring Liner with Lip, 2 Inch, Black

 

Those would work. I will have to search where I got them. It's been a long time ago, had them on my 2012.

 

Yesterday I removed the AAL and thoroughly greased all surfaces. I also greased the OEM leafs. No more squeak. Was not a fun process but totally necessary.
