SOURCE: Very rough idle on 2002 Jeep Grand Cherokee Limited Edition V8

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.

SOURCE: 2001 jeep grand cherokee wont reverse in

This could be an issue with the shift solenoid , but can also be caused by low fluid due to a leak, check your fluid. Is there a check engine light on, if there is it could be a solenoid issue.

SOURCE: 2001 Jeep grand cherokee motor knock 4.7 motor

First, if the noise is from the upper part of the engine and is more of a tapping than a knock, likely you have a problem in the valvetrain, most often a bad lifter or worn rocker arm. If the noise is low, deep inside, the noise is from a bearing. This is generally accompanied by lower than normal oil pressure. Regardless of the underlying cause, correcting the cause will not stop the knock. To do that correctly, the engine needs to be removed and all crankshaft bearings and the crankshaft itself need to be replaced (crank can sometimes be "undercut" and thicker bearing shells can be used depending upon the amount of wear.) If caught very early, sometimes only one bearing can be replaced in-car, but in 99% of all cases I have ever seen, most will fail again, sometimes more severely if done this way.

How do i know if my 95 jeep grand cherokee laredo 4.0 inline 6 is an interference engine


You have a timing chain that is good for the life of the engine. The only thing that could need replacing is the chain tensioner if it starts to make noise.

Do you need to change the timing chain on a 2003 Jeep Grand Cherokee at 75,000 miles?


You will not need to change a timing chain unless you know or suspect it to be bad. Belts and other material that wear down need to be changed but the timing chain itself is a metal similar to that of a bike chain but much shorter and thicker

How do i change a Timing Belt Tensioner on a 1995 jeep grand cherokee v8 5.2 my belt burned in 2 it and i need 2 take it off n replace it


You really need a repair manual for your model. Most Auto parts stores carry these. However, If your timing belt has been broken (burnt) while the vehicle was running, then you'll need to check for bent valves or cracked pistons. If you are not one, you may need a mechanic.

2000 jeep grand cherokee 4.0 liter engine timing belt replacement


If you have the same pulley arrangement that most 4.0 engines have that pulley is an idler not a tensioner. Your power steering pump has a pivot bolt, and a slide under the pump. You adjust belt tension using the pump.
