Are you experiencing Death Wobble? Or is it just a unbalanced tire feel. Death wobble is usually from worn out parts with brand new lift parts. It can be a loose track bar, worn tie rod ends, bad ball joints and if it is lifted over 4.5 inches it can be the caster is off and the front diff is rotated so far forward that the wheels are flopping around like crappy shopping cart with a floppy wheel.
You have to get under it with the front axle supported either on the ground or with jack stands under the axle like it is on the ground and push and pull stuff to check for loose and worn parts. If it is lifted up more than 4.5 inches longer lower front control arms will help.
The problem is 90% of the Cherokees that people fix up are worn out in the front end. Jeep skimped on the size of parts for the XJ and most of it is smaller than it should be for the abuse they get off road. V8 ZJ front end parts work great for upgrading our XJ's.
So, people buy XJ's that have 180K + miles on them and wonder why it shakes like a mother when they put huge tires and or lift on them. Every bit of slop on the front end translates to movement. Death Wobble.
Tie rod ends, wheel bearings, tie rod and ends, ball joints, track bar and even the steering box can make your front end shake. A lot of hard used XJ's have torn frames where the steering box bolts to. It is just boxed sheet metal and with bigger tires flexes the steel like bending a piece of wire until it breaks.
Anything that moves, pivots, rotates, flexes or turns needs to be looked at.
Or the tire could just be out of balance.

 

I just taped everything off on mine, windows, cowl and any other holes. Although I get a little dizzy on a long drive, my interior is SPOTLESS!
Just kidding.
I wish they had cabin filters. Especially when you are on a trail stuck behind someone on a dry, dusty day. Cough! Cough!

 

Ok guys I managed to save all my gas ima drop the tank tomaro what I did was I disconnected the hose from my fuel filter coming from my fuel pump and ran wire from my fuel pump spot to the positive bat terminal so my jeep pumped it out instead of me spy honing it

 

Okay. I've done my 10 minute search for my topic (that turned into an hour and a half) so, before I post this in another forum for the general public, figured I should ask here.

Just came into a base '90 Cherokee. I'm NOT turning it into an off-road beast (not yet, at least) I just need to get it back into decent stock condition. So I'm not looking for lift kits or brush guards or anything else like that.

I'm just looking for the BEST (ok, cheapest) online suppliers of decent replacement parts such as tail light assemblies, window cranks, dome lights, lift supports for that damn rear hatch that I have to prop open with a sledge hammer handle, console, etc., etc., etc...

That kind of basic interior and exterior stuff. (Other than having to replace the radiator, and all belts & hoses, it's running like a champ.)

So I've been to US Auto Parts, CarStuff.com, and a few others. Any that I should avoid and any that folks would recommend?

And in searching for these replacement parts I keep coming across mainly two manufacturers: CROWN and REPLACEMENT. (Yeah, I didn't think "Replacement" was really the company name at first be it seems to be...) Is one better than the other or are they both POS and I should be hunting down used OEM?

Thanks so much in advance...

Best,

CJ

 

I have bought stuff from all three of these places and they are really good. But for the best deals, U pull it yards are the best deal usually.

Oreilly Auto Parts has a good deal on the hatch struts. I bought mine from there and they were $19 a piece. I also used one of the old ones for the hood. It works great and is plenty strong enough to lift the hood and hold it up. And I am just using one strut on the hood. I bought the ball socket brackets for the hood at a camper shell place. You can buy them online too.

 

Ive been looking into buying a cold air intake for my jeep and had a few questions i thought come of you might have good answers too:
is there any other parts i should consider upgrading if i do install a intake?
what brands would you recomend?
does a cold air intake truly increase horsepower and torque like i have heard?
are they really worth the price?
do cold air intakes improve milage at all?
thanks

 

thanks for the information! ive checked out all the tie rods,ball joints, and steering components. how would i know if the caster is off like you talked about? im new to working on everything on my jeep so i really appreciate the advice. also is there a good way i can check the wheel bearings?

 

Will my 99 distributor work on a 00 motor if i remove the coil setup want to be for sure about it beferoe i throw down the cash for this motor

 

How do I tell what transfer case and which Danas front and Back I have in a 1990 XJ Limited. Trying to replace the Dif covers but research shows a couple options for this year an model. Any help?

 

Thanks, Modrod.

Any opinion, anyone, on the relative merits of Crown manufactured parts vs. Replacement brand parts?

BTW, Replacement Brand makes a pair of lift supports for the rear hatch for $23.14 (for the pair) through CarStuff.com. Just hate buying junk if that's what it is. (And I have an O'Reilly's one block from my house; might check and see who makes theirs...)

Thanks again,

CJ

 

hit your local jeep dealership an have them run the vin for a build list, mine was free but i've heard of others getting hit for 5 bucks or so.

 

try rockauto online, thats where advance gets stuff they can't find

 

Front is going to be a Dana 30 unless someone swapped it out. Rear will be one of the ones in this photo:

 

A real cold air intake (not a warm air intake, which is basically a high-flow filter in the stock location!) will absolutely improve performance and economy. Coupled with a free-flowing exhaust this makes a lot of sense: gains made by making it easier for the engine to breathe in won't be fully realized unless it can breathe out, too.

Here's a nice reference regarding ACTUAL results of performance modifications on the Jeep 4.0L: http://www.jpmagazine.com/techarticl...ies/index.html

This is a nice little package that will do just that: http://www.rustysoffroad.com/jeep-pe...-cherokee.html

However in this kit, and commonly in DIY situations, the filter just ends up in the stock location where it pulls in warm/hot engine bay air. Some folks have built air rams to get fresh air from between the drivers side headlight and radiator. Check out this thread for some ideas: https://www.cherokeeforum.com/f67/to...ations-107035/ A proper snorkel that is basically an air ram at roof level, while using the stock air cleaner, also qualifies as a cold air intake.

K&N seems to be very popular for high-flow filters. I personally don't trust them since a smaller filtering media moving more air than the larger stock filter doesn't make a lot of sense to me when considering long term damage by not filtering as effectively.

I'm a huge fan of this writeup, which addresses the warm air issue as well as proper filtration. The guy noted a 1.5 MPG increase on a long trip from the filter upgrade alone. Check it out: http://jeep-xj.info/HowtoAirFilter.htm
