I've got a Grand Cherokee Ltd 5.2l 1997. Lately I've been noticing that there is a strange noise accompanied with a vibration at the moment I accelerate going uphill. It feels like something kicking from between the engine and the back of the car just right under the driver's feet. It gets worse if I push the throttle any harder. I'm suspecting it might have something to do with the transfer but it surprises me that when I am driving on lower altitudes the problem seems to vanish away. So could that be anything related with the engine?
Thanks for your ideas!

 

So update rear diff cover off no welding open end. Took sway bar off helped a little with turn noise but right wheel still hops off ground when turning tight. Leafs seem to have no spacers in between them they all have a lot of movement in them. Any thought?

 

Here is what I did with mine, dump a can of Sea Foam in it , run it for about 100 or so miles change the oil, left mine drain overnight, I use 15-40 diesel oil, has more detergent in it, buy a quart of MotorKote at Wal mart and add about 10 oz to the oil. I did use a high flow pump and had no problems, other then getting the pan off and on. Might want to check your rod bearings too. I used .001 under size on mine, should have used .002 but couldn't find any at the time. Good luck

 

for my 2000 xj i want to get brighter head lights, can i just buy better bulbs or do i have to replace the whole headlight ?

 

Whole headlight. They're sealed beams which means the bulb is sealed in the housing.

Options:
Silvania Silverstar headlights
H4 bulbs with new housings
Truck Lite LED headlights

The first two would both benefit greatly from an aftermarket lighting harness such as Putco or eAutoWorks.

 

Put these,

(Could probably find them a little cheaper if you look around a little)

 

for the bulb do i select h4 then?

 

Yes, pm'd you

 

What's the advantage of the Olympus LED bulb over the TL sealed beam LED? Or is it just price?

 

Price, our LEDs with good housings are half the cost.

 

Pretty sure it is.

 

We have our own Comanche section now!!

 

just got 4 2013 jk rubicon wheels for my xj brand new for $100! i need to get some spacers and ive seen that spidertrax is the most recommended. any one ever have any issues with them?

 

You need adapters. Spidertrax is the right choice.

 

They are the best you'll get just have to get 5x4.5 to 5x5 adapters
