Toyota recently announced a TSB (Technical Service Bulletin) for the rear suspension squeak noise on 2005-11 Tacomas.

Tacoma Squeaky Leaf Spring TSB

Toyota has released a TSB to address a squeaky leaf spring suspension issue.

Toyota states that:

Some 2005 – 2011 model year 4×4 or PreRunner Tacoma vehicles may exhibit a squeak noise from the rear leaf spring when traveling over speed bumps or with suspension movement from loading and unloading the suspension. A new leaf spring pad has been made available to reduce the noise.

This TSB only covers specific 2WD, 4WD models of Tacoma’s including:

  • Access Cab
  • Double Cab
  • Regular Cab
  • Long Bed

Owners of the model years affected and those who fall within Toyota’s Comprehensive Warranty (36 months or 36,000 miles, whichever occurs first, from the vehicle’s in-service date) are encouraged to contact their local Toyota dealer for repair instructions.

Repair Procedure
This repairmay be long and complex based on which type of leaf spring you need to replace and it is recommended you visit your local Toyota Service Center for replacement.

The first step is verify the noise is coming from the leaf spring.

  1. Confirm noise is present by jouncing (bouncing) the rear suspension.
  2. Take and lift the vehicle by the frame to allow the rear suspension to hang.
  3. Carefully place a rag between the spring insulator and the leaf spring.
  4. After jouncing it while hanging, lower the vehicle and jounce the vehicle. If the noise then goes away, you know the source of the noise is the leaf spring pad.

Take note, after you are done isolating all the pads using rags and the noise continues, the noise is then NOT from the leaf spring pad. As such this TSB doesn’t apply.

Using a pry bar, you will need to separate the leafs.

Next determine whether you have a 3-leaf spring or a 4-leaf spring. Both procedures require you to:

  1. Use a large pry bar to separate the leafs.
  2. Take  a pick, punch or screwdriver to push upward on the the pad from the underside.
  3. Separate, remove it and discard.
  4. Clean all the grease and dirt between the leaf springs while not applying any new grease.

The 4-leaf spring repair procedure requires you to remove an additional leaf spring prior to installing a new spring pad.

After removing all the effected leaves, it is time to install a new spring pad with the reverse of the removal procedure. When finished make sure the vehicle is test driven to verify repair.

  1. I can’t find it in the article….does anyone know the TSB number for this? The only one I can find is the harsh ride TSB number, but I need the one for the squeak mentioned here. Thanks!

    • Hi Tyler,
      Did you ever get a reply to your question, or find out from Toyota about what the TSB number is for the squeak? I bought a 2008 last summer and I’ve noticed the squeak.
      Thanks, and enjoy your Tacoma!

  2. I’ve had taken my 2012 to local Dealership for the spring noise and it went away for a couple of months and now its back. Its really sad that Toyota is having so much issues. This problem was also addressed with my brakes squealing and they put a silicon on it and now the noise is back after a couple of months. It only tells me that toyota is working on patchy jobs rather than full fixes. I don’t have faith in Toyota anymore.
