Okay guys so about 2 weeks ago I towed a car behind Claire using a u-haul. The drive was good until I pressed the brakes. I could feel the pressure on Claire. Some idiot cut me off when it was raining and I had to slam on my brakes. Sshe started making this drag noise and I could feel this vibration under my gas pedal. Now whenever I shift out of park to reverse or drive I get this "CLUNK" sound. Not cool. And every time I coast I get this vibration and noise, but it's not the same as when I blew my differential. Should I rebuild the shafts just for peace of mind and to mark it off my list?

 

Do you have the rotoflex coupler on your rear drive shaft? If you do, i would check that to make sure it's not cracked/missing chunks. Also check your u-joints. You can always remove either the front or rear shaft then take it for a spin with the diff lock engaged in "HI" to help narrow it down. My front u-joint that was closest to the transfer case went and i started to get a "clunk" when shifting from park to reverse/drive and a CRAZY vibration when accelerating.

 

Alright I'll look and take some pics, I didn't know I could take off a shaft at a time and drive haha

 

Don't take pictures, we know what they look like. What you need to do is see if the Rotoflex is cracking between the six bolts, if it it is replace it. How often do you grease your 4 u-joints and the 2 slip shafts, if not twice a year, then replace all 4 u-joints and pray you haven't let the slip shafts go dry, tearing up the splines or you will be buying 2 new drive shafts.

 

Just to give you an idea of cost, to replace two u joints with Neapco one's at a shop here in Houston cost me $90...the u joints were $40 each plus $5 labor to install per u joint. To balance the shaft would have been an additional $50. I would recommend getting your shaft balanced (insert funny joke here).

 

You know I'm from Houston, TX too? :]

But uh.. should I get the upgraded rear drive shaft? Then redo the front one? I don't want to mess with rotoflex couplers busting everytime.

 

Yes, get your shaft upgraded...

If you need to replace the rotoflex, and can spare the money to upgrade, then upgrade. If you can't spare the money, then replace the rotoflex and u-joints. I think that anyone that can afford to take their shaft to a shop for rebuilding, can afford to upgrade.

 

Okay so upgrade the rear shaft, which has the roto and then rebuild the front shaft? Sorry english is complicated xD

 

Dude, seriously, leave the roto flex, just replace it with a OEM one.
The Cheapco u-joints are $10 each at AutoZone, you need 3 of them, both propshafts use the same ones.
Grease them at EVERY oil change and after every deep water crossing.
You cannot afford the rear propshaft conversion.

There are cheaper kits out there, but they are still more than the OEM rotoflex.
