I do not know your particular vehicle well, so some of this may not apply to you.
Bear with me, I drive "Real Jeeps" and think they should all be built that way---Example CJ 5 started out in 1955 and ended in 1983 that's 28 years of production (it did change a bit over the years)----Going by the Forum numbers there are 91 Questions concerning itThe Cherokee has not got near as many years and has 9255 Questions concerning it.
(I rest my case!)
Does your starter drag or labor or turn slow to crank over your vehicle?
Does it not mesh in well and sounds like it's grinding when it 1st engages?
Anyway, I have a couple of possible solutions for you, the last one may not apply!
DO YOU HAVE A REPAIR MANUAL?---I HAVE MANY FOR MINE--AND ONE STAYS IN EACH VEHICLE FOR EMERGENCIES!
1) Is your Battery sized to your vehicle correctly?
2) Replace Old Frazzled Cables--and Crappy connectors, clean connections---ALL from the Battery--on the Solenoid--wire to the Starter--connection on the Starter----and the GROUND WIRE on the ENGINE---TAKE THEM LOOSE--"DO NOT JUST SAY THEY LOOK GOOD!!!" (a little labor now may keep you off of the side of the road.
3) Do you have BAD KEY HABITS?.... Continuing to "Start" after its cranked up and running....Or "Cranking" while it is already running?
4)Your FLYWHEEL TEETH may be badly damaged from previous starters---Now ruining the newer ones you put on----Pull the Starter and look at the flywheel teeth...you MUST!!! BE CAREFUL--CHOCK THE WHEELS AND INSURE THE BATTERY and COIL are disconnected---Vehicle in NEUTRAL and use a BIG SCREWDRIVER or similar to roll it around and inspect it thoroughly (Put a mark at the starting point)
And last, If your STARTER CAN BE "SHIMMED" get a set of shims from the AUTO PARTS STORE and install WHAT IS NEEDED ONLY!
Looks like Autozone has a universal type (below)
Ask THEM---WILL THIS WORK ON YOUR RIG--DESCRIBE YOUR SYMPTOMS--ASK HOW TO CORRECTLY INSTALL THEM AND WHICH THICKNESSES TO START WITH--YOU CAN "OVER-DO" This!
OK NEXT STEP-INSURE YOU COME BACK HERE AND LET ME KNOW YOUR FINDINGS--I DO NOT GET PAID FOR EACH ANSWER AS THE OTHER FELLERS DO--THIS IS MY HOBBY AND ALL I GET IS A SMILING OR SAD FACE FROM MY "VICTIM"
LETS KEEP IT A SMILE!
