Whats wrong my abs light is on, my brake light is on and my speedometer nor odometer are working? 2004 jeep grand cherokee larado 6 cyl 4.0 liter

The speedometer on a 2004 Grand Charokee gets its signal via the PCI data bus from the ABS control module. Both rear wheel speed sensors are used for the speed signal.

You can do it in chassis but you will have
the trans out to do the seal. It is much easier to pull the engine at that point. The 6 cylinder is not that bad to remove.

1-1/4" or 32mm
buy and use a caliper to measure bolts.

Since alot of things rely on data from the speed sensor you will "usually" get an ABS alarm, little or no shifting,no indication of speed on the speedometer, and the check engine light. without the abs light and with a speed indicated I would lean toward a transmission problem

You may have a faulty sensor, most cases a wheel speed sensor, the light is on warning you that you do not have abs basically your car will stop like an old 70's model car before abs. abs atands for anti lock brakes, it keeps your brakes from locking up under extreme braking.

it is problem with abs control unit, replace it for testing purpose and try it.

First off, if you have a 2004 Grand Cherokee with the 4.0 liter 6 cylinder engine, then it is an inline 6 rather than a V-6. To answer your question, it has a timing chain.

you need to change the coil on# 3
