Question about 1999 Jeep Cherokee

1 Answer

Knocking noise when accelerating

It's loudest when I first start my Jeep grande Cherokee leredo (2000) but then only happens when I step on the gas.

Any ideas of what this could be. I do need my transmision drained.. could this be it? Just had the front tire rod replaced.. can't be this.

Help!

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.

Have a 2004 jeep grand cherokee and when i push on the gas peddle it makes a knocking noise and the heater seems to have gone out at the same time


Heater 'gone out' = low coolant. Knocking noise = internal engine damage? Maybe low coolant = internal engine damage.

You need a trained technician to listen to this, but it sounds like a connecting rod and or a crankshaft main bearing noise. I lean more towards the rod knock form a worn out bearing.

I have an '01/'02 Grand Cherokee Laradeo, when I slow down the oil pressure drops to zero, when I accelerate it goes back up. There is a quiet knock as well, this just started happening. Pleas


If there was no noise when it went to zero I would replace the sending unit by the oil filter for a few dollars. If it is a light ticking and it is all the time I would replace the bad lifter but if it is more clanking or thumping you have problems. If you disconnect one plug wire at a time and run it for a few seconds and the noise goes away that cylinder has a bad connecting rod bearing. I would pull the oil pan and replace the bearing. Or just replace crank and connecting rod bearings and get rid of it

Knocking noise is generally from the engine. What is your oil pressure? If pressure is low and oil is reasonably full, refrain from driving it till the cause is determined. Noise can also come from the transmission or transfer case but more likely it's from the engine.It can come from sticking valve lifters (moderately bad to potentially serious) connecting rod or main crank bearings (always serious) or piston slap (annoying, expensive but not terribly serious unless very bad) Piston wristpins can also knock but are very rare in todays pistons. Either way, this is not an item to ignore.

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 !!
