This procedure covers the inspection and replacement of exhaust rubber hangers on the 2019-2024 Toyota RAV4 2.5L I4 FWD to eliminate rattles, sagging exhaust, or failed rubber mounts.

Warnings

Tools required

Parts

• Exhaust rubber hangers × 4 — Use OEM specification

Preparation

1. Ensure the exhaust system is completely cool to the touch
2. Park vehicle on level ground and engage parking brake
3. Place wheel chocks behind rear wheels
4. Raise front and rear of vehicle evenly to working height
5. Support vehicle securely on jack stands at all four jacking points
6. Spray all hanger mounting points with penetrating oil if rusty or corroded

Procedure

1. 1

   Locate exhaust hangers
   Inspect the exhaust system from underneath. The 2019-2024 RAV4 2.5L FWD typically has four rubber hangers: one near the mid-pipe connection, one at the resonator, and two near the rear muffler. Note which hangers are cracked, torn, or sagging.
2. 2

   Remove heat shields if necessary
   If any heat shields obstruct access to the hangers, remove the retaining bolts using a 10mm socket. Keep track of bolt locations for reinstallation.
   Torque spec

   Heat Shield Bolts10 Nm (7 lb-ft)
3. 3

   Support the exhaust
   Have an assistant support the exhaust pipe section near the hanger being replaced, or use a jack stand with a block of wood to gently support the pipe. This reduces tension on the hanger and makes removal easier.
4. 4

   Remove front/mid hangers
   Working from front to rear, use a pry bar or exhaust hanger removal tool to hook the rubber hanger and pull it off the mounting bracket. The rubber grommet may need to be worked back and forth. If extremely difficult, apply more penetrating oil and wait 5 minutes. For the mid-pipe hanger, pull the rubber loop off both the exhaust pipe tab and the chassis bracket.
5. 5

   Remove rear muffler hangers
   The rear muffler typically has two hangers on either side. Use the same technique to pry the rubber hangers off their brackets. The exhaust may drop slightly as hangers are removed; ensure it remains supported and does not contact the underbody or suspension components.
6. 6

   Inspect mounting brackets
   With hangers removed, inspect all metal mounting brackets on both the exhaust and chassis for cracks, excessive rust, or damage. If any bracket bolts are loose or damaged, tighten or replace them now.
   Torque spec

   Hanger Bolts20 Nm (15 lb-ft)
7. 7

   Install new hangers
   Apply a small amount of soapy water or silicone lubricant to the inside of the new rubber hangers to ease installation. Starting at the front, hook one end of the hanger onto the chassis bracket, then use the pry bar to stretch and hook the other end onto the exhaust pipe tab. A rubber mallet can help tap hangers into final position. Do not use petroleum-based lubricants as they degrade rubber.
8. 8

   Check exhaust alignment
   With all new hangers installed, check that the exhaust pipes hang evenly and have adequate clearance from the underbody, fuel tank, and suspension components. There should be at least 25mm (1 inch) clearance all around. Adjust hanger positions if needed by rotating rubber grommets slightly on their brackets.

Reassembly

1. Reinstall any heat shields that were removed, torquing bolts to specification
2. Remove jack stands and lower vehicle to the ground
3. Bounce each corner of the vehicle to settle the suspension and verify exhaust does not contact any components

Verification

• Start the engine and listen for any exhaust leaks or unusual rattling sounds
• Have an assistant apply throttle while you inspect underneath for movement, leaks, or contact with the underbody
• Take a test drive over various road surfaces and listen for rattles or buzzing noises that indicate exhaust contact
• Re-inspect hanger positioning after 50-100 miles of driving to ensure hangers have properly seated
