Just did OME suspension change on TJ - UPDATE

Dec 19, 2004 13 Replies

Hi All,



Finally the weather gave me enough break to do the body lift and motor mount lift. Body lift went okay (except for the front grill bumpstop extensions which required taking light bezels off - part not included in the instructions). Motor mount lift on a 4.0L with air-con is a big pain, especially the passenger side (rather driver side for the Americans). Its doable, except for my torque wrench is too big to fit in that space so I'll have improvise a little when I do re-torque after a little use.



As for the shakes, well acceleration vibes are all gone. The only thing left is now a slight wobble as I start from stop at a turn. If I start from stop in a straight line, the wobble is not noticeable. Its just that when I start while making a sharp turn it wobble a little. What could this be?

You mean like suspension kinda jumping and jerking... mine does that. It's common on lifted TJ's from what I have been told. With some TJ lifts you can pull one of the front tires (don't remember which one) off the ground while starting in a turn.

If someone can tell us that this can be corrected, that would be great!

Yeah, my kid's TJ does this after we did the "Redneck Lift" on it. We've also been told by a local shop that it's normal for a lifted TJ. Makes me glad I've got leaf springs.

Slow down when turning...

This happens when accelerating from a stopped position. If I slow down any more, I would still be stopped (or would I go back in time?)

Don't accelerate so much?

That is exactly, it feels like something is flexing. One of the guys in our local club said it was because of the taller tyres (more flexing in the sidewalls). Sorry about the late reply, I was in hospital for a couple of days (nothing serious now).

Ahhhhh, a Civilian Jeep...... I'll find one in New Zealand and buy it (one day).

Now that I am thinking about it, I could feel a little bit of that as soon as I changed from smaller tyres to my current ones. Could it be because of the sidewall flexing under weight and torque? Its good to know that its not related to the driveline.

You can't really go around a bend quickly or sharply in a TJ, especially with a lift...

But the problem is when starting off on a corner.

I do have a limited slip in the back. It is all coming together now. Taller tyres all around, limited slip in the back, front tyres in a bind on a hard surface, things start having fun with each other. As long as my driveshaft and other driveline components are not ready to punch a hole through the floor board or rip themselves to pieces, I can live with this form of an occasional shake (rather wobble).

Thanks TW

I can live with that. It is just that I had done the lift and was testing all shakes and wobbles. I have managed to eliminate all others, except for this one. My question was geared primarily to get a bit of assurance that none of the major components are in immediate danger of catastrophic failure due to inappropriate angles or binding.

I'll let the suspension settle a bit and see how things go from here.
