Mitsubishi WORKING ON THE CHAIN GANG
Mitsubishi reports that certain instructions were missing from the repair manuals regarding timing chain inspection for the 2010 Lancer, Lancer Sportback and Lancer Evolution. Affected service manuals include 2010 Lancer, page 11C-17, Lancer Sportback, page 11A-18 and Lancer Evolution, page 11A-17.
TIMING CHAIN ELONGATION VISUAL CHECK
NOTE: When the timing chain elongates more than the specif ed length, the DTC P0012 (variable valve timing advancedangle value abnormal) is set. Unless the code P0012 is set, the visual check is unnecessary.
THE MISSING INFORMATION:
After the DTCs P0016 (crankshaft/camshaft intake position sensor phase problem) and P0017 (crankshaft/camshaft exhaust position sensor phase problem) are repaired, it is necessary to delete the learning value of the timing chain elongation. At that time, perform the visual check.
NOTE: Unless the work using scan tool MB991958 is correctly carried out due to the malfunction of the ECM, carry out the check whether or not the DTC exists.
• Storing the learning value regarding the amount of timing chain elongation before
ECM replacement. • Writing the learning value into the new
ECM after ECM replacement.
1. Remove the ignition coils. 2. Remove the cylinder head cover. 3. Remove the upper chain guide. CAUTION: Always rotate the crankshaft clockwise. 4. Rotating the crankshaft clockwise, align the timing mark of the camshaft sprocket with the point on the upper plane of the cylinder head. As a result of this, the No. 1 cylinder is positioned at the compression TDC. 5. Look at the inside of the timing chain case with one eye in the direction of the arrow. Fix the eye line at the point where the top axis line of the chain elongation indicator at the front side of the timing chain case is overlapped with that of the chain

Chrysler CHROME CLAD WHEEL BALANCING
Chrome clad wheels used by many OEMs have presented problems. Chrysler notes that the use of proper wheel adapters are required (on your balancing machine) when mounting chrome clad wheels to the balancer.
This affects all Chrysler vehicles equipped with chrome clad wheels, ranging from 2002- 2012, including Pacif ca, Ram truck, Durango, Aspen, Journey, Wrangler, Avenger, Nitro, Liberty, Challenger, Cherokee, Chrysler 300, Magnum, Compass, Patriot, Dakota, Caliber, PT Cruiser, Town & Country, Grand Cherokee and Commander.
Models equipped with chrome clad wheels require specif c piloting on balance equipment to properly center the wheel to prevent damage to the chrome clad surface. The chrome cladding is not removable or replaceable and has cladding tabs that extend into
the wheel bore. Traditional high-taper cones will come into contact with the cladding tabs rather than properly seat on the hub bore chamfer. Many modern aluminum wheel designs cannot be mounted with traditional cones. Direct-Fit collets should be used to properly mount clad wheels to balance equipment. The required adapter kit is available as P/N 1-20-2382-1. A special adapter kit is required to mount chrome clad wheels to your balancer. 1. Direct-Fit dual taper cone; 2. Seated in wheel hub (properly piloted); 3. No obstruction to cone; 4. Obstruction keeping cone from piloting; 5. Not seated properly in wheel hub; 6. Traditional high taper cone. Mercedes MERCEDES DELIVERANCE
This TSB affects all Mercedes-Benz models 204 and 207, with regard to a design change for the headlamp mounting banjo bolts.
The latch for the banjo bolt for the headlamp mount is no longer needed. Therefore, the new part is now screwed onto the lamp frame using a thermoplastic nut. At left: Changed banjo bolt (delivery condition). At right: Modif ed banjo bolt for the 207.
The new banjo bolt is available as P/N A 001 997 01 01 (subs to A 000 997 78 01).
Nissan CLICKING NISSAN
A clicking noise has been reported coming from the rear axles during take-off/acceleration on 2004-2011 Nissan Armada vehicles built before Aug. 14, 2010. Remove and clean both rear axle hubs. Apply a minimum of 1.0g of Molykote M77 grease (P/N 44003-7S000CM) to the axle hub bearing surfaces, in an even coating, where the bearing surface contacts the rear axle. Re-install the rear axle hubs, using new bolts and using a new torque specif cation of 152 ft.-lbs. to 160 ft.-lbs. for the rear axle nuts. Test drive to conf rm the incident is
