Squeaky TRD Pro

Hey all,

I recently purchased a used 2017 TRD Pro from a local dealer. Overall I love the truck, however the dealership wasn’t great and they seem to have snuck a few lemons through that I didn’t notice... (the truck was due for an oil change only 300 miles after purchase, the cabin air filter was filthy, etc.) Recently I’ve noticed increasing squeak on my rear end. Slow bumps and any braking while reversing causes the whole back side to creak like an old truck. It’s only 4 years old, with 40k. I used dry lube on as much of the leaf springs as possible and it helped but it’s definitely still there. Has anyone encountered this? I am taking it in to a local mechanic tomorrow but will they be able to help? It’s super hard to pinpoint the source, even underneath while my wife or kids jump in the bed. I was already annoyed by the dealership and their shoddy “120 point whatever” but now I’m thinking they knew the problem and effectively masked it. Any tips would be appreciated. Don’t want to have to drop a huge chunk of money into making my truck not sound like a ‘92 Jimmy.

 

Got my 17 Pro with 34k on the clock a little over a year ago. No issues with a squeak. Hope you can hunt it down and get it fixed. Best truck I have owed.

 

Got a 17 TRD PRO and have squeaking anytime I brake. I looked at all of the brake pads and they are all fine and don't need to be changed. My guess is that they didn't put any anti-squeak on the pads but it doesn't affect performance. I take it on trails but don't notice any crazy creaks.
I also have an alignment issue. It's been an issue since I bought the truck. Supposedly it had an alignment right before I bought it but took it to a tires plus and bought the lifetime warranty. So far I'm 5 trips deep with them and they haven't fixed it so I'm trying a different shop.
Other than those issues I haven't had any problems. Hope this somewhat helps you and congrats on the purchase!!!

 

Are you sure the oil wasn’t changed? Could simply be they didn’t reset the light. IMO I would change the oil and filter anyway that way you know what’s in it and not some discount oil.

What's the overall condition of the truck. Does it look well taken care of or did a farmer own it? That should help you determine if it was well taken care of. The cabin filter could be a sign but then again not everyone knows it’s there.

I would personally get the oil and all filters changed. Then jack the truck up with the wheels removed and flush every nook and cranny under the trucks rear with a hose

Can you post pics? Maybe you have an add a leaf or something else aftermarket that’s causing a squeak. Those are notorious for being loud

 

The truck was in tip-top condition other than the 2 things I mentioned. I called the dealer and the salesman said they didn’t perform an oil change because it wasn’t due... duh. Not a good look. Again, the truck is great other than the squeak. There is a lock-key on the spare tire lowering cable which was no where to be found. Annoys me endlessly too. I had read on a forum that some people found the squeak came from their spare. I can’t lower it, because there was no key with the jack. So I’m waiting on that $40 key in the mail. Thank god I didn’t have a flat when I discovered that!

I don’t think there’s an extra leaf or anything aftermarket. The shocks are stock TRD Pro. But I was under there lubing the leafs and didn’t see anything unusual. My profile pic is the truck. It’s clean and not in bad shape anywhere. The whole thing is so strange. But I’m going to take it to my local mechanic and have him do what you suggest. Thanks!

 

Occasionally my truck develops a squeak from in-between the leaf springs. Get a can of whatever you got with the little plastic straw extension and blast in-between each one. I've had to blast it out a handful of times over the last 5 years. Hope you find it, squeaks suck.

 

check the bed bars, underneath bed and above frame. Where it meets. Mine was creaking there. Sprayed some silicon wd40 and it went away.

 

yeah I did that with wd40 dry lube. But probably not enough. It did help a little but I didn’t drench it, and I probably should have.

 

I have to really make a mess. I shove that straw in the side and back until it blasts out the opposite side. Get your shoulder under the wheel well and rock it up and down. You'll know pretty quick if its the issue

 

it absolutely sounds like it’s coming from the bed, at least the more groaning noise I hear. I’ll try that but it’s hard to see what you’re referring to

 

phone to the rescue
see below. You can still see some of that silicon run off.
hit them all with some silicon wd40. I think 2 on each side.

 

The spray lubes don’t usually last.
I’ve experienced this with multiple leaf springs.
The best method I found was to use moly grease or red tacky grease.
It needs to be applied to the leaf spring pads that are at the end of the leafs in between each other.
Jacking up the rear by the hitch receiver and shoving a pry bar in between the leaves make it easy.

 

@all thanks for the reccos and help. I ended up taking it to a spring shop and they took apart and cleaned my left side leaf springs and reassembled. It mostly fixed the issue. I suspect some of the noise came from polyurethane bushings but they cleaned those too. If it starts again any time soon I’ll probably get new bushings.

 

Not a Tundy, but all of my Tacoma rear squeaks always came from the front leaf spring bushings. The shackle bushings never seemed to squeak.

Used silicone spray lube to stop the squeak and also other lubes that were supposed to be bad for the bushings.

Seemed like any spray lube would do the trick.

The spray grease stuff seemed to last a bit longer.

Park on the street and hose away, then drive immediately to work it in before the carrier evaporates. Or have the wife jump on the rear bumper while spraying.
