Death Wobble?
Hey group,
I am experiencing a wobble in the front end of my 86 CJ7. It is slight and I don't feel it until I hit about 65 mph. I think it's probably a wheel balance problem but just in case....... What causes the dreaded "Death Wobble" commonly associated with short wheelbase 4X4's? I heard of it and seen it on Jeeps, Broncos and IH Scouts, usually at speeds in the 40-50 mph range, but have never heard a definitive answer on the cause or the fix. I'm sure somebody out there has the answer. Thanks, Charles |
Re: Death Wobble?
Can't speak for the CJ, but when it happened in our ZJ it nearly
scared us to death. It was a combination of loose stuff in the front end. Had to replace the steering stabilizer, track bar, tie-bar ends and drag links. That solved the wobble. The last fix was to replace the stabilizer bar link bushings. It's like new now. I'm sure your problem is somewhere in the same areas. A good front-end man can tell you by watching things move while someone turns the steering wheel back and forth. ---- On Thu, 10 Feb 2005 21:15:34 -0600, "Ervin Charles" <charleserv@charter.net> wrote: >Hey group, > I am experiencing a wobble in the front end of my 86 CJ7.

If you feel edges going one way and not the other or cupping it's time for new shocks. DW at a specific speed it 99% balance. Rotate the tires front to back and got for a drive. IF the DW goes away have the tires balanced. If the DW stays, replace the stabilizer. -- -- DougW -- 93 ZJ 4.0 http://members.cox.net/wilsond HESCO Supercharger - 300W IASCA Stereo - Edelbrock IAS Shocks Gibson Exhaust - rear DCpower - custom gauge install - Stillen Rotors Banks Header - and BEER, in the fridge! |

Re: Death Wobble?
I had a bad case of this in my TJ late last year and the guys here
recommended new tires. I went out and got a set and the difference was UNREAL. Like a new Jeep! When I looked at the 4 old ones next to each other, one of them was pretty far from round. Matt |
