Pry Open "Spare Tire" Flap This automotive maintenance tutorial was specifically created to assist owners of the showtime generation (2001, 2002, 2003, 2004, 2005 & 2006) Acura MDX with the SH-AWD system in changing the VTM-4 fluid in the rear differential.

Owners of other Acura or Honda vehicles such equally the RDX, ILX, TLX, RLX, TL, CL, RSX, RL, TSX, ZDX, NSX, Integra, Pilot, Accordance, Borough, Fit, Clarity, CR-V, CR-Z, HR-V, Odyssey, Element  and Ridgeline may as well find these DIY instructions to be helpful.

The only fluid that can be used is genuine Honda or Acura VTM-4 which is part number 08200-9003 or 08200-9003A.

The replacement crush washer (or "gasket") sizes and part numbers are as follows: Drain Plug 18mm 90471-PX4-000 and Fill up Plug 20mm 94109-20000.

The tools needed to complete the procedure include a small plastic pry bar tool, a 3/8" bulldoze ratchet, a prophylactic mallet, a new automotive fluid pump, a torque wrench and a used oil catch container.

The maintenance schedule for changing the VTM-4 fluid in the rear differential is every 30,000 miles under "normal" driving conditions or every 15,000 miles for "severe" driving such every bit towing, frequent curt stop-and-go trips, mountain driving or driving off road.

Some of the symptoms that point the VTM-4 fluid should be inverse include a judder, shudder, shake or vibration noises from the rear terminate of the SUV while turning. This is acquired by the fluid being contaminated with worn away clutch material.

Flip Open Hinged Cover
Spare Tire Nether Cargo Expanse
Rotate Counterclockwise Park the SUV on a level surface, turn off the ignition, engage the emergency / parking brake and chock the front end wheels to prevent the vehicle from moving.

For the easiest access to the rear differential, I recommend lowering the spare tire.

Open the tailgate door for the cargo surface area.

Locate the minor plastic admission cover for the hoist mechanism that lowers and raises the spare spire.

Lift open up the rear border of the cover with a plastic pry bar tool or a flathead screwdriver.

Remove the lug nut wrench (or "tire iron") from the storage compartment on the left side of the plastic cargo expanse panel.

Place the socket on the lug nut wrench over the hoist shaft.

Slide the spare tire over out of the way where you lot won't trip on it.

Now would also be a good time to check the status and air pressure level of the spare tire. If necessary, inflate it to 60 PSI.

(I didn't desire the spare tire cable and block in my style, so I raised it by turning the hoist shaft in the clockwise direction.)

VTM-iv Rear Unequal
Tools, Pump & Fluid
Electric Touch on Wrench With the spare tire removed, you lot'll easily be able to see the VTM-four warning sticker, the fill plug and the drain plug below it.

The rear differential's total fluid chapters is 3.0 U.S. quarts. For a drain and fill, the differential requires 2.9 quarts.

So y'all'll only need ane gallon bottle of Honda 08200-9003 VTM-iv fluid. Afterward three rear diff fluid changes, you'll have enough left over fluid to complete the quaternary one. Just be certain to go on the left over fluid in one bottle with the cap tightly sealed.

Slide under the rear of the SUV with the 3/8" ratchet, a rubber mallet, a fluid pump, the used oil grab basin and the gallon jug of VTM-four fluid.

If y'all are unable to loosen the fill and/or bleed plugs that have been over tightened in the past or take corroded from salt water exposure, yous tin use an electric affect wrench with a ane/2" to iii/8" drive socket adapter.

Filler Plug Removed I highly recommend that you start remove the fill bolt at the tiptop of the rear differential.

If you first remove the drain bolt and then are unable to remove the fill up bolt, you won't be able to drive the SUV until the make full commodities can exist removed to supersede the VTM-4 fluid.

Both the make full and drain bolts accept "square" holes which are to be loosened or tightened with a three/8" bulldoze ratchet.

New Car Fluid Pump
Insert Rubber Hose
Pumping In New Fluid Attach the new automotive fluid pump to the height of the gallon VTM-iv bottle.

The VTM-4 rear differential is known to be sensitive to fluid contaminations. So avoid re-using an former fluid pump that has been used for the transfer case gear oil or the rear differential on a unlike vehicle.

Insert the hose into the filler hole at the top of the differential.

Continue pumping in the new fluid until yous see information technology start dripping out of the filler pigsty.

ii.9 Quarts Pumped In
Re-Use Erstwhile Washer The rear differential fluid capacity specification for a drain and refill is 2.9 quarts co-ordinate to the service manual.
