3 Separate Issues.

[ftpiercecracker1]

Here we go gents, I've got 3 problems that should be fairly simple to resolve, but we all know how that goes.  :shake: 

 

 

 

Issue #1:  I have swapped in a V8 ZJ sway bar and links, WJ lower control arms, and new shocks, but i still have an excessive amount of body roll as well as very poor on road manners. Just driving down the road the steering feels all over the place, made expontentially worse if the road is waffly/uneven/ has dips or pockets.

 

I have also swapped in a ZJ steering box (quick steer ratio :rock on: ) BUT, it has a definate dead spot which, again, adds to the instablity.

 

What i think the problem is. . . .  Sway bar links and bushings are shot, and the steering box needs to be rebuilt. I was also contebplating adding a second bracket so that the bottom portion of the sway bar link could be captured on both sides.

 

 

 

Issue #2:   At low speeds and take off, the truck will sometimes shake roughly and get worse with the amount of power applied (standard transmission) but will stop every time just after take off. It likes to do it particuarly bad when taking off and turning at the same time. It does something similar in 4wd as well. Usually when there is lots of wheel spin and i am turing fairly sharp. The shaking in 4wd is VERY rough and forces me to let off on the gas and/or straighten the wheel. However, I do not think the two issues are related.

 

What i think the problem is. . . . . . I believe the problem i have while driving under normal circumstances is my pilot bearing. It is either worn out, or no longer firmly pressed into the crankshaft, allowing the shaft of the transmission to wobble around (shaking) until it self centers (at 5mph) (physics and all that)

 

The problem i have while in 4wd, i do not have any ideas. My Universal joints (drive shaft and axle shaft) are in good condition and my wheel bearings are brand new Timkens.

 

 

 

Issue #3:  At speeds greater than 65mph the truck has an annoying shake/vibration. At 55/60mph its smooth as glass. Upper and lower Ball joints (XRF) and Wheel bearings (Timken) are brand new, installed last week. Track bar has less than 1k miles on it, all steering components are new (less than 1k miles), draglink, tie rod, and all TREs. As stated previously, i have JY WJ control arms, V8 ZJ sway bar, and ZJ steering box.

 

Its not a severe shaking, as i was doing 80mph the other day, its just annoying as hell.

 

 

What i think the problem is. . . . . I considered getting the tires balanced, but i have learned that tire balance only really comes into play at 55mph, which i have no problems running. I still have the factory aluminum rims, the ones with the fake looking bead lock (10 hole) and it was discovered that 2 of them were warped. I swapped them out for JY ones and doing so took away 80% of my original shaking.

 

I am at a loss as to what my next move should be, new rims, tire balance, or new track bar maybe? :hmm:

 

 

 

 

FPC.

#3 to me sounds like a  Loose or worn out trac-bar.

 

Could either be the bushing end on the passenger side, The ball joint end at the driver side, OR The bracket that mounts to the frame for the trac-Bar

Jump under & Give a good yank on it, & see how tight the bracket is.

 

Could also be causing some steering issues in #1, I know mine did when the bracket was loose.

Over the weekend I installed the WJ LCAs from a 2000 at the PNP and my steering went to $#!&.

 

Are your LCAs new or used?

 

 

I took them off it was so bad.

Are you running any lift?

Also, how aggressively do you wheel it? I jumped my ZJ once ( I know....) and had horrible vibes above 50. Thought I had it narrowed down to a bent wheel. Much to my surprise, I had bent the passenger side axle shaft (!?!?) of my Explorer 8.8.

Mine are from a JY too, but i tried to find a good pair. Compared to my originals the WJs are brand new fresh out of the box.

 

EDIT: it had the vibes before any of the aforementioned modifications.

I wish. The only thing i have on is a 1.5in spacer to help out the horrendously sagging coils. Other than that it is stock ride height.

Even though i do wheel her occasionally, I have never even come remotely close to going airborn. I try to take it easy on the old girl as she is my DD, but i get out once in a while and sling a little mud, maybe get stuck once in a while, but i try my darndest not to thrash her.

#1, worn track bar bushings as mentioned, or worn WJ LCA bushings. 

 

Worn pilot bushing and a worn input bearing on the transmission may be causing #2 and #3.  That definitely can cause that shaking on take off.  For #3, does it do it at highway speed while under power or also coasting at high speed?  Drop it in neutral when up to the speed it happens, if it still occurs that may rule out the transmission but it could also be a worn ujoint, wheel balance, or driveshaft issue.

The mud comment stuck in my mind. What wheels are you running? Back when I had Flat 5's on my ZJ, mud would collect inside thr inner ridge of the wheel. I wouldn't notice that it was there, even after pressure washing, until I got uo to certain speeds and it would cause the world's worst destb wobble. Freaked me the hell out the first time it happened. Long story short, I switched to Canyons.
