The cause of the yellowing is oxidation caused by UV exposure and wear and tear from normal driving. It can be only a minor haze or it can be enough to seemingly block all of the light from the bulb. The cure fr this problem is an inexpensive bottle of scratch remover. You can find it at just about any auto parts store for a few dollars. Once you have the scratch remover you will first start the repair process by thoroughly cleaning the headlight to remove any soil that could further scratch them. Then read the directions on the scratch remover and apply the polish to the light using a clean soft rag. Rub the scratch remover on the headlight for several minutes and then remove it with a clean rag. You might need to use some pressure so don’t be afraid to bear down a little but. You also might have to repeat the process several times to remove all of the damage. Repeat this process on the other headlight

In 1993, Jeep launched the fine-looking Grand Cherokee in response to the success of rivals Ford and their Explorer model. The Grand Cherokee saw Jeep produce a vehicle with their legendary off-road capability but with an improved highway ride and larger interior than the Cherokee.

Initially three models were offered: base model, Laredo and Limited. Jeep stole a march on competitors in the market place with the inclusion of driver’s side airbag and all round anti-lock brakes. Notable standard features included full instrument set, cloth interior and 5 speed manual transmission. In addition to this the Laredo came with body cladding, powered mirrors and cruise control. The Limited came with leather seats, Air Con, upgraded stereo system, 4 speed auto transmission and a host of powered parts.

The construction and design of the Grand Cherokee led to a 105.9 inch wheelbase, 4.5 inches longer than the Cherokee leading to more legroom for rear passengers, also the Grand Cherokee was only available as a four door model.

The engine for the Grand Cherokee was the Jeep 190 BHP, six cylinders 4.0 liter and towards the end of 1993 a 5.2 liter V8 with 220 BHP was launched. This larger engine gave a great advantage over the Grand Cherokee competitors and also allowed for a towing capability of some 6,500 pounds.

In 1994 the Grand Cherokee saw refinements made including all round disc brakes on the Limited, rear seats gained headrests, power sunroof and upgraded stereo system. The base model was renamed “SE” and side impact beams were fitted in the doors improving crash protection.

For 1995 Jeep introduced the “Orvis” edition Grand Cherokee in response to Ford’s Eddie Bauer (both Orvis and Bauer are outdoor clothing and equipment manufacturers). The color scheme for this was green paint, red and gold accents and two tone green & champagne interior. Other improvements were increased torque output from 285 – 300 pounds for the V8 engine and deeper tints to side and rear windows. Two new optional extras were available with a flip up tailgate window and integrated child safety seat. Also a two wheel drive version of the limited with six cylinder engine only was launched.

According to the German tuning company, “The Jeep Grand Cherokee has arrived and STARTECH presents an exclusive refinement program for the SUV. The extensive product lineup is characterized not only by its professional engineering and innovative design: All components also offer exceptional quality. For the 3.0 CRD model with common-rail turbodiesel engine STARTECH offers the SD6 performance kit and a particulate filter.”

The bold and aggressive body styling of the Jeep Grand Cherokee 3.0 CRD model was enhanced by STARTECH exterior design cues, which include the STARTECH front apron with integrated design elements, STARTECH rear apron with cut-outs for the two oval chrome tailpipes in the STARTECH sport exhaust system, STARTECH side skirts with integrated entrance lights, and STARTECH chromium plated mirror covers. The sport exhaust system is made of pure stainless steel and available for all engine types for the Jeep Grand Cherokee.

In addition, the five doors of the Jeep Grand Cherokee come with STARTECH door sills with integrated LED lights that can be activated by using the standard keyless-entry remote or with the door handles. The Jeep wheels have been replaced with the high-quality STARTECH Monostar IV 9Jx20 light-alloy wheels. It features five-spoke wheel design wrapped with Yokohama tires measuring 265/45 ZR 20 both in front and rear. This completes the exclusive exterior package of the STARTECH tuning program for the Jeep Grand Cherokee.

Inside, the Jeep Grand Cherokee comes with an exclusive interior design from STARTECH.

Chrysler Group’s popular SUV features STARTECH leather dark slate grey interior trim, which is highlighted by a bunch of STARTECH interior accessories including the ergonomically shaped sport steering wheel with a leather cover. Other customize interior features include STARTECH floor mats for passenger compartment, STARTECH mats for the trunk, and polished stainless-steel sill plates with illuminated STARTECH logo.

The folks at Chrysler’s Street and Racing Technology (SRT) group could not leave well enough alone. From the Neon to the Viper and from the 300C to the Ram pickup truck, no model has been too sacred to receive a proper work over from the team. First it was a bevy of Dodge models, then it was the Chrysler 300C, but no Jeep model had yet been targeted for the group’s overhaul. The Grand Cherokee however was past due as fond memories of the GMC Typhoon likely played a part in the decision to inject “SRT steroids” into a widely acclaimed Jeep model. Indeed, the SRT group knew that 0 to 60 in five seconds with the Grand Cherokee would beat the Typhoon’s numbers by about four tenths of a second, easily making the Jeep model the all time leader on the road as it is already off the road.

Much like the full size SRT cars sold by Dodge and Chrysler, a 6.1L Hemi V8 was the engine of choice for the SRT team tasked with building the beefy Jeep. With 420 h.p. and 420 lb.-ft of torque, the burly Hemi would serve duty in the Grand Cherokee SRT8 along with 20 inch Goodyear performance tires, Bilstein shocks, four piston Brembo brakes, a Quadra-Trac On-Demand four wheel drive system, and a capable five speed automatic transmission. Indeed, when the project was completed, the SRT8 was paired against the Porsche Cayenne SUV and the Jeep won!

If the SRT8 isn’t fast enough for you or if you want to experience a rich, deep tone while driving, then the aftermarket parts industry has just what you need.

Magnaflow Exhaust has developed a performance exhaust system that pairs well with the Grand Cherokee SRT8. Developed from airliner quality stainless steel, a Magnaflow Exhaust delivers more horsepower, frees up more torque, and provides a rich tone not found on the typical Jeep exhaust system.

When it comes to air intake systems, Dubair and Airaid have induction systems that work great with your engine. Dirt is filtered out and cool air is invited in to deliver more horsepower, enhanced torque, while offering a deep, throaty tone that is certain to inspire you.

Jeep Grand Cherokee Noises – Roaring noises, are one of the most common sounds a Jeep Grand Cherokee makes from the rear end. As I mentioned before, if roaring noises are heard this should be addressed as soon as possible. Typically around 45 MPH is when sounds will start coming from the rear end. If roaring is heard at all speeds or at parking lot speeds, the problem has progressed. Roaring noises are from worn and pitted bearings. Carrier bearings (which are the side bearings) are the most common bearings to fail. Next are the pinion bearings, especially if a pinion seal has been replaced at some point and the bearing preload was excessive. This means the pinion nut was tightened too much. Over-tightening the pinion nut can cause an excessive load on the pinion bearings and can wear the bearings in a short period of time. If the bearing replacement is postponed too long, metal can travel through the differential oil and damage other moving parts in the differential. This can cause accelerated wear of the ring and pinion gears. So if they are caught early enough, the bearings can be replaced without replacing the ring and pinion gears.

Ring and Pinion gears that are worn excessively make a whining or humming noise, sometimes on acceleration and sometimes on deceleration. And they are more expensive to replace than just the bearings. The ring and pinion gears can make a whining noise without a roaring noise being present from the bearings. But when replacing the ring and pinion gears the other bearings, including two pinion bearings and carrier bearings are recommended to be replaced also. The axle bearings should be inspected but they are the farthest away from the differential gears and bearings, so they most likely will be OK especially on lower mileage vehicles.
