DESCRIPTION
Some vehicles may exihibit a vibration in the accelerator pedal and steering wheel when accelerating during a sharp lefthand turn. An abnormal noise may also be heard from the footwell area. This may be caused by insufficient clearance
between the engine mount stopper rubber and the engine mount bracket.
Customer may state:
• Vehicle shudders/vibrates on left turns, most often when accelerating from a stop or entering a driveway.
• They feel a pop or grind in the accelerator pedal when the vibration occurs.
• They hear a rumbling or grinding noise, mainly from the right side, during the left-turn shudder.
NOTE: The condition does not occur at shallow steering angles or when the vehicle is stationary and the steering effort
remains unchanged when the vibration and noise are present.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify the customer concern.
NOTE: DO NOT use power tools in this procedure. Use hand tools only.
2. Disconnect the negative battery terminal using the procedure in [NEGATIVE BATTERY TERMINAL
DISCONNECTION/CONNECTION].
3. Remove the engine cover.

(4) Stopper rubber
(5) Engine mount
(6) Engine mount bolt
5. Remove the right front (RF) tire using the procedure in [FRONT UNDER COVER REMOVAL/INSTALLATION].
6. Remove the front under covers (splash shields) No.1, No.2, and No.3 using the steps
in [FRONT UNDER COVER
REMOVAL/INSTALLATION].
7. Remove the mudguard bolt and fastener.
8. Remove the right-side (passenger side) front splash shield No.2 using the procedure in [FRONT UNDER COVER
REMOVAL/INSTALLATION].
9. Remove the nut (left image (1)) from the engine mount (left image (3)) and loosen but DO NOT remove the engine
mount bolts (left image (2), right image (1)).

NOTE: The engine mount bolts are easily accessed with a 36-inch (90 cm) extension from above. A 1/2 inch drive is
recommended because it flexes less.
10. Remove the engine mount stud.

11. Support the engine with a jack, but DO NOT lift. A screw jack is recommended as it is more precise with lifting and
lowering. NOTE: When jacking up the oil pan, insert a cushioning material between the jack and the pan (e.g., a large
wooden block that extends beyond the oil pan and protects it).
NOTE: If using a transmission jack, make sure it does not interfere with the crossmember.
12. Insert the cushioning material between the jack and the oil pan.
13. Loosen, but DO NOT remove the three right-side member bracket (subframe) bolts (1).
14. Loosen, but DO NOT remove the two crossmember bolts (2).
15. Remove the bolt that holds the heater hose bracket (3) to the right engine mount.
NOTE: The outer bolts (circled yellow (2)) are for crossmember (subframe) bolts. The center bolt between these 2 is the
bolt that goes through the engine mount (when looking straight up at the A-arm). The hole through the A-arm bracket is
where a tool extension goes through to remove the bolt for the mount. This is the bolt in step 2 below (yellow circle).

l. Use a floor jack to lift the engine until the mount and bracket touch.
NOTE: When jacking up the oil pan, place cushioning material (e.g., a rubber pad or wooden block) between the
jack and the pan.

o. Ensure a zero-contact position before tightening.
1) Zero-touch position (1).
2) Lightly push the engine-mount stud (2) with your finger; if it can be moved only slightly, you’ve reached
the 0-touch position. If it moves freely without much resistance, lower the engine slightly and recheck.
Page 12 of 17
06/11/2026 02:35 PM tlawrenc
3) Verify that the stud (3) and the engine-bracket bolt holes are aligned in the same positions as shown in
the photo.
■
■
If they are not correctly aligned even in the zero-touch position, shift the stud bolts or the engine laterally to
achieve proper alignment.
DO NOT over-lift or under-lift the engine during tightening.
NOTE: Before tightening, ensure that the engine mount and engine bracket are in a zero contact (0touch position), and that the position of the stud bolt and the bolt hole in the engine
bracket matches the OK position shown in the photo. If the position is not in the OK location even
in the zero contact (0-touch position), manually adjust the engine position. Be careful not to tighten
the nut while the engine is excessively jacked up, as this may lead to loosening of the
fastening. Also, avoid tightening the nut when the engine mount and engine bracket are excessively
pressed together (i.e., when the engine is not jacked up enough), as this may result in excessively
small clearance between the engine bracket and the stopper rubber.

NOTE: The image below shows an engine that has not been lifted enough (1) or an engine that has been
lifted too high (2).
4) Lightly tighten the mount nut to 5 ft-lbs (6.8 Nm) on the engine mount stud.
5) Raise the vehicle and measure the gap (left image (1) between the engine bracket (right image (2) and
the stopper rubber (right image (1) using a taper gauge or stacked feeler gauges.

• If the gap is below the specified value, return to the previous step and recheck that the stud bolts and engine
bracket are aligned in the correct position, then adjust their alignment.
• If you cannot achieve the required gap by adjusting only the right engine mount, remove the nuts that secure the
left engine mount and engine bracket, and shift the left mount to place it in the centered position, as shown for the
left mount (no gap measurement is required on the left side).
• If you still cannot adjust the gap within specification after adjusting both engine mounts, replace both engine
mounts—performing the replacement one side at a time, following this procedure. Loosen the crossmember bolts
one side at a time; loosening both sides simultaneously may cause wheel-alignment deviation.
• When replacing with a new engine mount, it is not necessary to transfer the stopper rubber to the new engine
mount.
19. Install the right front (RF) tire using the procedure in [FRONT UNDER COVER REMOVAL/INSTALLATION].
