Weird death wobble problem.

[travypoo]

Hey guys, I have a 93 240sx and I am getting some crazy steering shake.

Here is a video of what is happening:

Also another video of a guy having similar issues (he has the same knuckles and longer Flcas , maybe causing issues when ran together?)

death wobble in my s14 sketchy! - YouTube (http://www.youtube.com/watch?v=2yn4-PTQEqM)


Front end parts include:

MAX RC knuckles
s14 OEM FLCAS
Abercrombie sub frame, rack moved forward
Tein tie rods
MAX rack spacers
18x9.5 +15, 225-40-18, 10mm slip on spacer, tires balanced
New steering rack was just installed
newer wheel bearings and balljoints
Fortune auto 510 coils
all bolts and nuts were checked, no play in anything up front

6.7 caster, -4.4 camber, 0 toe

I had this problem last year and put on 0 offset rims up front with the same tire and no spacer and the shake went away. this year it came back with new front wheels.

The only thing I can think of is the PS pump, or just crazy death wobble from the knuckle, rack relocate, control arm combo..so odd though that the different rim offset made the shake go away though

Any help or suggestions at all would be so great! Thanks!

Just read the FB comments and you said so far nothing.
You said it's not the rack and pinion, also I couldn't see the tie rods going in and out.
Maybe the wheel hub? Either the bearings might have gone out due to not torquing them enough on to the knuckle.
Also have you tried to run without spacers? You said you had 10mm spacers so do you have longer wheel studs?
Have you "bent/dented" those wheels, if so maybe they're warped.

In the second shot you are able to see the tie rods moving, tough to see though. newer wheel bearings and trqd to fsm spec and I checked them through the year. I tried no spacers last year with no luck. all wheels are brand new out of the box and right onto the car after tires were mounted/balanced. I have nismo 60mm studs as well :) thanks

hmmm.... Have you tried throwing it off a cliff?

[travypoo]

That is the next thing to try haha

Sounds to me like your problem might be the spacer in there. Remove it and add hub centric rings 66.1 to guessing what your wheel is 73.1. Might be the solution.

I'm interested to see the solution..

Tried a 15 mm hub centric spacer with hub rings. Still shook. Tried 5 mm spacer with different wheels and tires and didn't help. Tried no spacers with just hub rings and didn't work either

[travypoo]

no spacers at all did help though. i had to drive around the block a few times for it to shake

I have this same problem when I run my starion wheels. It ran fine on brother's tacoma, but when I put them on my s13, I had this horrible violent shaking above 55mph. Haven't found a solution yet.

I just figured it out. It has to do with wheel offset for some weird reason. I had only a 15mm bolt on spacer available. Since my lugs are extended I had to pound out the spacer lugs. Slide them on, wheel still shook hard. But then I used the small lugs they give you for the spacer. I bolted the spacer right to the factory lugs. Put my wheel on and problem gone. So odd. But it worked. It made the new rims the exact offset as the wheels that worked last year.

That's weird, at least you figured it out.

i had similar shaking around 55 mph if was slower or faster than 55 everything normal. was fixed with hub centric rings no spacers.
