MML or T-Case Skid Drop for Vibrations

Holy vibrations batman! Just finished lifting Bonnie and the vibes are intense



She still needs a few things, rear bumper to hopefully even out the rake, front trackbar to be relocated, etc. To combat the vibrations I have a 1" MML which I read could be installed without a BL. Does anyone think the MML would be enough to rid all of the vibrations for a 3" SL? I'm trying to avoid dropping the transfer case skid because of the dreaded nutserts. Judging from the condition of other nuts I've pulled from my frame I know it's going to be a crapshoot

Opinions?

I didn't want the TC drop either. Drove it that way for a month before installing a MML and a BL. Nothing wrong with both body lift and motor mount lift together. Angle is better now than with just the TC drop. Advantage of adding both together (MML and BL) is you don't have to modify or move the fan blade shroud.

A 1" MML MAY be enough to eliminate the vibes from a 3" SL but no guarantees, you may need to add a little t-case drop as well. If you don't want to install a BL with the MML, you can raise the fan shroud an inch by drilling new 1" lower mounting bolt holes in the fan shroud.

Whatever you do, fix the vibes asap, you can't just live with them since they will eventually start taking out things like u-joints, bearings, and/or seals.

Avoid the TC drop at all costs. That totally defeats the purpose of the lift you just installed.

If you can afford it go with the sye/new shaft. There isn't a better way to go then that IMO

Honestly I was expecting vibes but these are intense and really surprised me, I drove it down the street and that's the extent of travel she'll see until I address this

I definitely will be going in the direction of an sye/ds but I'd like to do everything related to it at once, tummy tuck, sye/ds, adjustable rear uppers, rear adjustable trackbar and bracket but I need to save up before doing said mods (probably cost me a good $1500 right there)

I'm leaning towards trying the MML, at least it should help to some extent where I won't need 1" spacers under my skid, a few washers is no biggie. I was planning on doing an electric fan conversion which would rid me of the fan shroud but it will take some time. I might just redrill the fan shroud for the time being until I can install the e-fan, thanks for the suggestion!

Do you do deep water crossings? That is the ONLY reason I would ever contemplate an electric fan conversion.

Can you describe your vibes a little more detailed? It might be a totally different problem if they're as bad as I think they are.

That's a good point. My TJ developed a major vibration years ago that was surprisingly bad and it turned out that one of of the driveshaft's u-joints was not quite centered in its yoke after replacing it.

I recently put a 2.5" SL on mine about 2 wks ago and I too, am experiencing some steer vibes, not very significant but noticeable enough when taking off slowly in 1st and 2nd gear but goes away at higher speeds. I haven't installed my front adjustable track bar but will be doing that tomorrow and possibly doing a t-case drop. Will that be enough to fix the vibes?

Yes I do water crossings, some are deeper than others but I'd rather play it safe

The vibes are rear end and are present from 0-30mph, what else could it be from?

That doesn't sound like a camber problem. Jerry go! Not my field of expertise. I'd double check EVERY bolt you touched first incase something wierd happened. (my left rear shock came unbolted)

+1. If you can afford the lift and tires, you can afford this.

Like I said, I'll be getting one but I need something to get me going for the time being.

I just installed my 1" MORE MML. It helped the vibrations a decent amount but they still remain. Just for kicks I broke one of the t-case skid bolts and to my surprise broke pretty well and came out with ease. Here's to hoping the next 5 are the same I'm going to try to shim them with washers tomorrow and do some testing

Don't take all six bolts out at once. Leave the three bolts on one side loosely threaded in while you insert the spacers on the other side so it is easier to keep positioned.

Thanks for the advice Jerry. I had a brainstorm in the shower and I am going to wait to drop t-case skid until I put my groundpounderfab bumper and spare tire on the back. With the combined weight I am sure my suspension will sink in the rear and maybe hopefully help out cause more

The wheels are black rock 909s's (aluminums! ). I think they look great but I have two huge gripes with them. First, the "hub cap" is actually made of plastic and is secured on using a single hex allen bolt. You need certain lugs to fit underneath elsewise the caps won't fit on (i.e. my case, summit racing said a certain model would fit and I ordered them and they don't...). Second, they have this stupid 2 lug pattern design, to be compatible with 5x4.5 and 5x4.75 lug patterns so if you don't have the hub cap on it looks really bad. I'll snap a photo and show you

Some buddies suggested I get upper rear adjustable arms and it should help my problem. I was under the impression you need an SYE/CV prior to those. Any advice?
