Well...the work is being performed on my jeep now. One more question for you guys...should a posi switch be installed. What advantages would I have? I don't do much serious off-roading but do plan on going to the snow and doing some camping at some point. Mechanic says since the jeep is on the rack now I should go ahead and have it done. Any suggestions?

The 2 biggest advantages are reliability & 2-low. With the posi lock, you have the ability to use low range without locking the front axle. Comes in handy every now & then.

Okay guys...got the jeep back today and I'm pleased with the its new performance. I was able to keep up with traffic and was able to shift into 5th gear. Thanks for all you suggestions and support. As I have always said...if you can't find the answer in this forum...it doesn't exist. You guys are great!!!!
There's only one little thing....the speedormeter is a little off set. Don't know by how much. Plan on having a buddy drive in front of me so I can figure out by how much it's off. Any suggestions on how to fix this? Should the mechanic have corrected this? He's the one who told me about it before I experienced it.

Jeep Speedometer Gears at Morris 4x4 Center

Need to change out your speedo gear. Match tire size to the new gear ratio and that number is the gear teeth you need. REALLY easy to swap out.



Mine calls for 32 tooth. But I found a 40 tooth in it and according to GPS my speedo was off by about 12-14 mph (said 53, I was doing 64-65)

The speedo gear is already ordered and should be here in a few days. Now while I'm at it...I'm going to give the engine a little more pep. All I have is stock stuff in the jeep now. Guys...tell me what you think of these small changes:

MSD Ignition 6421 - MSD 6AL-2 Ignition Box
MSD Ignition 8228 - MSD Blaster OEM Replacement Coils
MSD Ignition 31689 - MSD 8.5mm Super Conductor Spark Plug Wire Sets
NGK Spark Plugs 7252 - NGK V-Power Spark Plugs

Glad you like the gear swap. Best bang for the buck by far even if it is a little spendy. That looks like a good list for upgrading the ignition. Swapping to a 4.0 throttle body really woke my 2.5 up. Well worth the 20 minutes it took to do the swap.

One last item. Any suggestions on choosing a good electric fan. New? Used Ford Taurus fan from a junkyard? Would prefer to go new but some of the reviews made me have second thoughts on Flex and Derale. What have been your experiences? Keep the stock fan?
