There is a very simple check for a loose timing chain due to a broken tensioner, worn gears, or a stretched chain. Pull the distributor cap and observe the rotor position. Take a breaker bar and a appropriate socket and put it on the crankshaft damper pulley. If you have a degree wheel put it on the damper pulley else you can just chalk mark the timing mark position at the appropriate time.
Now - slowly turn the crankshaft pulley in a clockwise direction. Watch the distributor and observe that the rotor is moving. Stop turning. Now - mark the damper pulley position with the chalk or observe the degree wheel. Very carefully turn the crankshaft in the other direction and VERY carefully observe the rotor in the distributor. The instant it begins to move STOP turning and mark the crankshaft position again. Measure the number of degrees of rotation of the crankshaft. If there is a lot of slop in the chain then you will have moved the crankshaft ten or fifteen degrees (or more) before taking the slop out of the chain after the reversal before the camshaft began to turn. Get the picture?? If all is well and there is no slack in the timing chain then you will see about three to five degrees of "reverse motion" before the distributor begins to turn.
There's NO WAY the timing chain and gears are bad in a 2003 model truck. I don't know what kind of problem that you are having, But I rest asure you it's not the chain and gears. Need more info about your problem.
Need to know where the timing chain gear marking are?
Timing chains have either a single or a double chain (duplex). The timing chain has at least 20 sprockets, and a tensioner. All of these parts do wear out and cause problems. Some timing chains are made of rubber and others are made of solid metal. The rubber ones usually have a recommended life, i.e. 50,000 miles. One problem is that if a timing chain breaks the valves or hits pistons, it will cost a fortune to fix. Another problem after changing a timing chain is if the gears weren't lined up when it was put on, or the tension was wrong on the timing belt. Usually there should be no more than a total of 1 inch of play. I don't know if the Chrysler has a rubber timing chain or metal, or what it would cost to replace the timing chain on this vehicle.
I need to know where the timing chain is located in a 1988 Olds 98 regency brougham, and how expensive a timing chain is.
i want to know timing chain nissan frontier marking
2.7 has chain, 3.4 (6cyl.) has belt
The 2.0 liter 4 cylinder has a timing BELT and the 2.5 liter V6 has a timing CHAIN
i have a 51 plate 2.2 cdx vertra i would like to know how to set the timing chain
It does not have a timing belt it has a chain
I know that the Kia Sedona from 2006 and on having timing chains.

It is not necessary to change timing gears when changing a timing chain unless they have become worn. You won't know if this is the case until you get the cover off and inspect them. It is necessary to change any chain tensioners when you change your timing chain.
