Hi i think my last post was lost for some reason., but here it is again, the knocking sound you can hear is probably the big end bearings worn, these are the shells that go between the conrod and the crank shaft , it sounds like they have worn either by lack of oil at some time, or just through age and use, this is also normally accompanied by low oil pressure light coming on but not always, 2 options you have are, another engine, or repair the bearings , but this will depend on how bad the crank has been damaged by the worn bearings..hope this helps please vote and rate thanks

Engine knock


caused by hot and lean.
which engine.??? at least 3 choices.
most have knock sensors. and will not knock.
if it really is knock then that is serious.
knock means detonation or ping.
if its just noise say that,
real PING happens under load.
1: check fuses.
2: check knock sensor for outside damage.
3: SCAN the PCM. do you have any DTC errors/
4: do a full 60k tune up. maybe its lean because the fuel filter is clogged.

My jeep has a knocking sound coming from the engine and makes the same clicking/knocking sound when I'm accelerating what could this problem be?


noisy lifters, or piston slap, i just had one where the piston went through the block, try on your next oil change putting a liter of tranny fluid in it with the oil, the better lubrication will settle a noisy rocker

Oil pressure guage pegs out when I accelerate--WHY


Check wiring to sensor on motor clean or replace.If that is OK.then consider: older high mileage cars will start to ware their bearing and causing more back pressure under load, you may have to live with it. Unless you what to rebuild motor.

93 jeep cherokee stalls on acceleration


sounds like it is not getting enough fuel. remove fuel filter to see if it is clogged. if no fuel to engine, when giving it gas it will stall out. if it is getting gas then the injectors may have dirt in them, use a good injector cleaner.

Knocking noise when accelerating


A few questions for you how many miles on the engine? have you had regular oil changes done? This model should have the 4.0 liter engine if so what you are describing sounds like rod knock. The 4.0L engine is designed to take allot of abuse and last for well over 200,000 miles but if regular oil changes are not done you are in for trouble. And the only way to fix rod knock to have the engine rebuilt.

Audible knocking in rear of 1993 jeep grand cherokee laredo with 150,800 miles knocking only occurs when accelerator is not pressed


Sounds as If You Have A Chipped Tooth On the "RING GEAR" in the Differential (Rear Alex).
Is this Where You Hear The Noise Coming from? If So Remove Diff Cover With One Wheel OFF The Ground Trans In Neutral Rotate Drive Shaft and Look Closely For ANY Abnormal Surface on EACH Tooth of RING GEAR= the Large one And The "PINION GEAR" the Small one. If you find Chip or Rough spot Diff Must Be Rebuilt. Beyond that A Pinion Bearing can Also Make A Knocking Noise But the "GEARS" Will Be a Rhythmic Noise. I Hope this is of Some Help To You Good Luck !!

Knocking sound that intensifies when drivng faster


It could be a drive shaft. You may need to go under the vehicle and see if there's any play at the joints that are on the ends of the shaft.
