I just got a 2002 7.3L Crew Cab! :D

Well the old rule of thumb was 400HP on PMR's. But this limit was set when tuning was not as great as it is now. If you could use a larger nozzle and less timing, you could keep cylinder pressures in check while still making good, safe power.

Stay tuned to Bill's thread, think this might disprove alot of previous assumptions.

So I took some pics of my U-joints a bit ago, i hope they upload here right, can anyone tell me off first look if they should be replaced?






Thanks for the help!
My thoughts are that it can't hurt, but if they look like they will be fine then I will spend my money on other things
Thanks!

I can't tell by looking at the pics, I've always just grabbed the drive shaft & shake & twist it to feel for any loose motion in the u-joints.

The one on the rear diff looks a bit funny to me.

What is that hanging off of it, the dust seal?

Yeah that it what it is as far as I can tell, I'll try shaking the shafts and see, I am planning on replacing them when I get time, do I need to worry about quality our can I just go to the local auto parts store? Thanks

so good news and bad news, good news: I figured out why my truck had a the vibration... bad news: I figured out that I have a BROKEN U-joint. The dust cover that Dave pointed out is hanging because that is where the joint is broken. I went out and got new u-joints and I am going to install them this weekend... :/ I hope it doesn't take too long, anyone have any ideas on how long it will take to do all 5?

If you have never done them before, should take an hour or two.....but if you have the help of someone who has.....under an hour from start to finish.


Couple tips:

• Be sure to mark the shafts before you bang the old joint out, this way it stays balanced.
• Grease zerks always point towards the driveline.
• Pay very close attention when installing the caps, one needle bearing that "falls down" will ruin your day.
• Be sure to "burp" the joint if they are tight after installing the clips. This is done by striking the driveline near the joint with a hammer. They should move freely without any tight spots.
• When greasing the newly installed joints, make sure grease comes out of every cap.
• Patience, patience, patience.

Good Luck!
