Vib ?

[mybigredjeep]

Ok i eliminated the death wobble, so now i dont -=-=-=-= in my pants. Now i have just a bad vibration i have a couple ideas of what it could be im going to list them tell me what u guys think it is if you think its something else also let me know.........

U joints
I might need to drop my TC
or new lower control arms

This is for a 94 GC with between 3.5 to 4 inches of lift thanx a head of time........

There is a whole lot it could be. If you want to start eliminating the easiest things first, check the u-joints by blocking the tires so it wont roll and with the trans and transfercase in neutral grab the driveshafts and check for play. If they are greasable grease the joints while your at it. look for dents in the shafts, that will give you some vibes. Also the shafts usually have weights on them at one end or the other-look for new rust spots where a weight might have been. We were all hitting some 4" thick blocks of ice a couple of weeks ago! With the brakes on have someone look under the rig while you shift from forward to reverse. See of the control arm bushings have a lot of slop. Also check the motor/trans mounts the same way. a little powerbraking usually shows bad mounts. Dont overlook wheel weights, I have knocked them off wheeling before. You could try rotating the tires too and see if that moves the vibes to a different end of the rig. To narrow it down a little does it vibrate under load? high speed or low? Usually you can get away without lowering your tc on a grand. Hopfully this helps or someone more familiar with grands will post up
good luck.

it starts at about 62 mph

[rockdawg]

Have you done anything new to it that may have caused the vibes to show up or have they been there since the lift was put on?

[dmxjg35]

if you dont have a t-case drop i would deff get that first more than likely that is your problem, get under there and look at your drive line angles espically your ds. see if you can spin it and see if it gets hung up at the ujoints

[XEON]

I have a few sets of t-case drops. If you want to drop by someday we can install one and see if it works. :) Let me know!

IM having the same problem ,this past weekend I got the 3" lift on , at first I thought I got away with the TC drop , but I notice that around 55/65 MPH I get a vibe , but only if I happen to hit a bump or something makes the XJ shake .....so Im looking to get a TC drop ,make one or I guess pay someone to make me one :roll:

probably u-joint vibes, get some 2* or 4* shims first and see if that stops the vibes.

It needs to get a aligment anyway so I'll wait to see if that's the problem

I have a new BDS Industries TC Drop kit that I don't need. It's for an XJ. $20 if you're interested. If you're going on the Group ride next Saturday I can bring it with me.

don't put off getting this fixed. my YJ had a vibe around 60 mph after my lift that i decided that i could live with for a while. a month and a half later my slave cylinder took a dump on me. it was less than a year and a half old. some 4° shims took care of the vibe that the t-case drop left. $400 for a $40 fix that i just kept putting off. :mad: if you've got an auto it might not be as hard to live with it, but it just goes to show that some mild vibes can cause big problems.

[mybigredjeep]

well hopefully i can drop it with some of justins extra drops.............(just wondering how much you would sell them for?) and that will fix it.......if not im taking it to the shop cause i dont wanna replace 900 bucks worth of parts if its just a 30 dollar fix ya know.............thanx for the input though

I'll take it , not sure if I can me it to the ride , for 2 reasons ...I dont have a hook point on the Jeep yet looking for a hitch something cheap from a junk yard and I just have a 215/75/15 spare and Im running 31's ...I guess a full size spare will be a 31 for me.

[ROCKREADYXJ]

OK start with the usual source of vibs the driveshaft what kind do you have is it a cv style or is it a fixed shaft with a CV?

How did you fix the death wobble?

Or did you just hide it?

[mybigredjeep]

I fixed it because when i put the new trac bar in i didnt tighten it down so all i did was tighten it and i am golden............that was a simple fix

[ROCKREADYXJ]

how about the rear d-shaft?

[XEON]

Ahh nice man! Good job now we can hit paragon alittle faster... wait nevermind we will be waiting for me... the YJ is slow 8)

[mybigredjeep]

OK ALL, Then never ending battle of the death wobble/vibs is completely gone...........1369 dollars later..............the wheel barrings were replaced, 3 ujoints and a rear axel seal.............the rig drives beautifully and feels great. feels like i just drove it off the lot..........im going to get in trouble before i had an automatic speedomiter and was able to tell exaclty when my truck hit 55 now its like driving a porshe.

:D :D :D :D :D :D :D :D :D :D :lol: :D :D :D :D

[ROCKREADYXJ]

1369 IT COST THAT MUCH for wheel bearings and u/ joints? I guess I ain't charging enough. good lord!

[mybigredjeep]

it also had an alignment and some other small things but those were the major things

Just move your shop out to Long Island, you can charge a fortune and nobody will think twice about it.

Drive out to Orange County I will give you a very fair price.
