Rear Spring Issue

I have an 09 TRD Sport with 13K miles. Lately I noticed a squeaking in the rear end when I get out of the truck and also if I push down on the rear bumper I notice it also. Wondering if the current spring tsb covers this issue as well? I have not noticed any harsh ride or bottoming out in the rear thus far but really haven't had more than about 300lbs. in the bed.

 

I would get the TSB done, with only 13000 miles on your truck the 3 leafs will only get weaker and cause problems. My 2010 prerunner has 7000 and the TSB was done last week...............HUGE difference, I do not think it is stiffer but just more of a positive feeling from the rear.

A few hours after posting this I was scrolling down to this post and saw at least 3 other posts referring to squeaking so I guess that tells me something.

 

my leafs squeak....and i have an off road 10-pack....it just sound...wont hurt anything

 

Depends on where the squeak is... you can squirt some silicone in the suspension bushings, if it's coming from there. On my first gen I would occasionally give the spring leaves a squirt of WD40 after washing the truck. It kept the noise down and kept things from sticking together. Not a big thing.

 

The squeak usually comes from the contact of one leaf rubbing against another. They have silencer pads that can be inserted between the leafs. Your truck is new enough I would take it to the dealer and either have the leaf spring TSB or the silencer pad TSB performed.

 

I have an 09 TRD w/ 13k too, had the TSB done for the last 6k or so miles. after i went wheeling they squeak, maybe some sand or dirt got it them.

idk, maybe bc it happened after wheeling it doesn't bother me, but it doesn't...

I just took mine in for the leaf spring TSB. The person I spoke with wasn't aware of the TSB for the springs, but did mention one regarding the leaf spring bushings being bad and causing squeaks. I noticed that happening the week before when I would drive over a speed bump slowly or even when the rear end would slightly lift when starting from a dead stop. Even happens when stepping on rear bumper.
They are replacing the bushing pads also when they do the spring packs. Invoice shows SSP for Spring squeak P/N 04009-09104.

 

I have ome dakars the bushings in the front of the leaf pack squeak like a MF. The conclusion I've come to is that ome uses a different bushing material than toyota and they squeak. I'll order new bushing from toyota one of these days and swap them.

 

My leafs squeak as well. It wouldn't squeak until after the first time I went to one of the trail runs and got mud everywhere. I was able to minimize the squeaking by using the pressure washer in between the leafs but they still squeak.. It's annoying but i'm sure there's nothing wrong with the truck.

 

Ive had this problem too on my 09 and took it to the dealer and they regreased the friction pads. There is a Service bulletin on it, not a TSB, but something like that and they should know of it and will regrease them for you. That fixed my issues.

 

There is a TSB. Here it is.TSB-0274-09.pdf

 

^^^ Sweet! Thanks for posting that!

 

I did have the truck to the dealer and that is exactly what they did, put in the new silencer pads that is.

 

A service bulletin is a TSB (Technical Service Bulletin)
