#57 of 170 Infinity Sound System
Sep 16, 2005 (3:22 am)
I've got a 1993 Jeep Grand Cherokee with standard am/fm cassette sound system. I just purchased a Jeep Infinity CD Sound System on eBay. It is supposed to swap out with my existing unit. I'd like to update the speakers too. Anybody know if this Infinity unit will need an external amplifier, or is it part of the unit? Any suggestions on what type of speakers I should get (mainly megahertz, watts type info, not necessarily brand names)? And should I invest in tweeters and a sub-woofer?

Ok, not to worry if the right things are done.
First, yes, you will have to do both differentials. You won't find a reputable transmission or ring and pinion shop that will only do one. The chances of a catastrophic failure are simply too great not to do them.
Second, make sure to go to a reputable shop. Changing out the ring and pinion is one of the jobs in a driveline that's very subject to experience. Getting things just a little wrong will result in plenty of noise and premature failure.
Here's a great link that talks about doing EXACTLY what you want to do. I agree with this page at 4.88's to be about right. link 4w4c gearing article
Also, realize that your speedometer is now off, and your braking distances are going to increase. This is more a function of the new weight of the wheels and tires over the stockers than anything else. Rotating mass and all. Be nice to the terrified Kia's and Scion's in front of you and brake early
Keep your speeds down until you're sure the lift kit is operating correctly as items like the track bar can cause "death wobble" if they're loose or worn, especially in lifted vehicles. This will cause a loss of steering to the point of a bad rollover on pavement. Your YJ handles completely new now, so you'll need to get used to it all over again.
Lastly, you didn't mention if you have new wheels. You probably do, as the stock offset should not allow clearance while running a 33/12.5. Since the offset is now greater, you might check on some flares, as people are actually getting tickets for tires outside the body (I know, I know, but it's a real law in some states. Seriously).
I've been through three different jeeps (YJ, XJ, and TJ), so I've sort of done this before. Hit the "Wrangler" message board for more technical questions, as many of the members are total Jeep-geeks and can argue points like the above for days, all while providing great advice or even pics if you need 'em.

I'm happy to read about someone installing factory foglamps on their JGC. My 01 Laredo did not come with them. Where did you buy yours? Did it come with switch to illuminate them? Did you have to cut your bumper to nstall them?
#60 of 170 Tire Upgrade on '05 GC

Has anyone increased their tire size without modifying their suspension? I put a set of 31" Dueler A/T Revo's on my 04 Wrangler Unlimited, very happy with the tire, and would like to put P255/65R17 Revo's on my '05 JGC. I found them for $173 ea., but not sure if they will fit. Any experience with this would be appreciated. By the way, very happy with my my loaded Loredo.

I put a set of 245/75 Yokahoma Geolanders on my JGC Limited 5.7 Hemi and they fit great. Since you are putting on a set of shorter tires, you should have no problem.

blkhemi, what do you mean by "shorter tire"? The 245's are the optional size, I am trying to get 255's underneath to fill out the wheel well. Do your tires with the 75 width clear the wheel well?

"75" is the number designated in regard to the height of the tire. 245 is the width. My buddy just put 265's on his '06 Overland with no rubbing whatsoever with the factory suspension. I chose the the 245/75 for increased ground clearance. They also make the vehicle ride a bit taller.
#64 of 170 tornado air management for jeep liberty

Has anyone used the tornado air management system on their Liberty to improve MPG. Trying to find out if it is worth the money or just a scam?

blkhemi, thanks for clearing that up for me. I bet it looks sharp. I think I will go with the 235/75R17 Revo's.

Good move yellowfin. You're right they do look sharp. I live in a remote area so I needed more of a sidewall than what the factory tires offered. I think the 235/75 Revo's will go great on your Jeep. Keep me posted on the outcome.
