Petrol
Check the transmission shift quality by gently accelerating in lower gears. | Note: It is worth noting that the 5-speed automatic can sometimes exhibit rough shifts as it ages; a smooth, consistent delivery of power is what you are looking for.
Turn the steering wheel fully to both locks while stationary. | Note: Listen for any audible groaning or whining from the power steering pump, as these older hydraulic systems can benefit from a fresh fluid flush if they feel a bit heavy.
Switch the transfer case through all settings (4-Hi/4-Lo) while at a slow crawl. | Note: It is common in these vehicles for the transfer case motor to become sluggish if it hasn't been cycled regularly; ensuring a smooth transition is a good indicator of health.
Test all electrical features including the sunroof, heated seats, and infotainment. | Note: Given the age of these vehicles, checking that every button responds correctly is a wise move, as aging wiring harnesses can occasionally cause minor gremlins.
Usually the time to evaluate the suspension bushings and shocks for any signs of perishing.
A common point to check cooling system hoses and the water pump to ensure the Hemi remains at optimal temperatures.
Recommended interval to review the integrity of the alternator and starter motor to ensure reliable daily starts.
Prioritize regular engine oil changes using high-quality synthetic oil to keep that Hemi V8 running smooth.
Keep an eye on the transmission fluid color and ensure it is serviced according to the manufacturer’s schedule.
Inspect the CV joint boots regularly; catching a small split early can save the joint itself.
Ensure the cooling system is topped up with the correct coolant, as these engines prefer a healthy thermal environment.
Monitor brake pad and rotor wear, as the weight of the Grand Cherokee keeps the braking system busy.
Estimated repair costs if issues arise
If your vehicle is equipped with the Quadra-Lift system, it is good to know that the rubber air bellows can eventually wear. Depending on the car's history, you might eventually need to budget for these to be replaced to maintain that smooth ride quality.
The Hemi engine is known to occasionally tick if the manifold bolts loosen or gaskets degrade over long periods. If this becomes noticeable in the future, it involves a bit of labour to access and seal back up.
If you notice firm or erratic gear changes later on, it may be time to look at the valve body. In cars of this age, refreshing this component can significantly improve shifting precision.
