The next thing I need to look at is the front-end. After I installed the Rancho stabilizer I noticed my front-end shakes when I hit a bump. Could it be a bad stabilizer or did I messed something up when I beat the hell out of the stabilizer bar to remove the stabilizer?
I know it sounds too simple, but start with the basics. Go back and make sure everything is tight. Look at all of the bolts and nuts (even the ones you didn't remove) and physically try to shake everything including the entire vehicle. I had a knock in mine after I finished the front end. I layed underneath the engine compartment while someone else shook the jeep. Turns out it was the T-case. The lever to engage 4wd got bumped and was halfway up. Start basic and then get technical.
A dry steering test is going to be the best way to figure this out I believe. Have a friend sit int eh driver seat with the jeep on while you get low enough to see what is happening in the front of the jeep. Have the friend turn the steering wheel lock to lock and see if anything moves: bushings, wallowed out mounts, joints... You will see something wrong and it you don't post up a video while doing the test.
Today I took my Jeep on the highway since I got my rear main seal fixed and installed the MML + BL. Around 40 - 60mph i'm hearing a noise and it's going to a pattern ( hope that makes sense), the faster I go the faster the noise gets. When i remove my foot from the pedal, the noise stops. I can also feel the vibe in the pedal.
- Still need to address the front end issues.
- Getting vibes after installing MML
- Had to bring back my Jeep to the dealer tonight because the rear main seal is still leaking
- Installed Black Magic rooters, calipers and pads.
Got my jeep back from the deal tonight. the problem was the oil pan gasket. I'm just glad it wasn't the rear main seal.
This weekend i'm planning on installing the Rokmen LCA's (if it's not to cold). This is my first time installing LCA's, I've watch a couple of videos and it looks pretty straight forward. any helpful tips?
I still have to install the springs, shocks and track bar. does it matter the order i install them?
Finally got the springs, shocks, LCA's, and rear trackbar installed today (thanks to http://www.liorclub.org/sponsors/evan/ Evan from Bay Shore). Only thing left is, tires and figuring out the vibes I'm getting around 45+.
Most likely the pinion angle. Make sure that the rear pinion is the same angle as the driveshaft at ride height.
If youre in a flat area and have enough ground clearance I find it easiest to put the transfer case in neutral so I can grab the driveshaft and turn it by hand. The jeep may move a few inches forward or back since youre effectively turning the wheels by hand, but it lets you get the pinion yoke right where you can take an accurate measurement with an angle finder. Then you measure the driveshaft angle. If they are different, use the adjustable control arms to adjust the pinion angle so that they are identical.
Did you ever fix your wobble you had from before? This is probably the same wobble magnified. Your pinion looks close enough not to matter in the picture above (it needs to be perfect, but it looks close enough no to cause the vibes you are talking about). Are the vibes coming from the front or rear? Did you spring/ride height change? You should do a dry steering test if you are getting vibes from the front and didnt correct them already.
