Question about 1999 Dodge Durango

1 Answer

98 DD 135K w/ Knocking (no noise)

My Durango started a violent knock (no noise) about a week ago.  It is most prevalent with a load on (up hill) - around 2000 RPM.  It used to be an occasional jolt, but now is much more frequent.  At first no issues noted on the Tach - now slight variance, and can feel it at a stop doing the same thing (less violent).  CHECk ENGINE light just came on.  Cleaned the air filter and put in fuel system cleaner with last fill up of 89 Octane (had been running on 87 fine for years).  Any suggestions?

A ticking noise is usually associated with sticking lifters or valves. A knocking sound that gets louder under load (like hills) is probably worn main bearings on the crankshaft

I have a 2004 Dodge Durango 4.7. About 3 months ago I replaced the oil pump, but believe it was the oil pick up valve that was the problem. 2 days ago, the engine began knocking loudly the entire time it...


Try using a MOPAR oil filter...These cheap after market filters are allowing the oil to drip down into the pan and there is none in the top of the motor on cold starts.

Knocking noise in the engine.


You have a Lifter and Rocker Arm Tapping. You will need to Take off the Valve Covers and Listen for the Tap. When you Locate it Tighten Down Until it stops and then Back it off 1/8 of a Turn.
