So I get really bad death wobble around 45-50. I just replaced the trac bar and it didn't fix anything, what could be causing the death wobble?

2000 jeep Cherokee xj
3 inch lift

 

Everything steering related as well as ball joints. Control arm bushings in rare cases.

 

Was it a full leaf/coil 3" lift and did you install an adj. track bar? First check the tightness of the track bar bolts and look at the U/LCA bushings. Then check the TRE's and if you installed larger tires upgrade the steering at least to a mid 90's V-8 ZJ unit much stronger and solid than stock and a direct bolt in no mods. The complete setup is under a $100 at AutoZone so cheap.

 

Everything stated above, but also check the axle side track bar mount and make sure its not wallowed out. Also did you replace your ball joints when you lifted it? Have you had a proper alignment?

 

Why don't people search? It's been covered 100 times if not more

 

I didn't replace the ball joints and it didn't need an alignment

 

full pack

 

Anytime you lift a vehicle it needs to be aligned. If you never did an alignment yourself or had one done, do it.

 

Yup you do need a full alignment. When you lift a Jeep it changes the castor which will cause DW in some cases. Also go ahead and swap your ball joints, unless they're practly new.

 

It also changes the toe drastically

 

Agree on the alignment. it should be only $50-$70. But make sure you call ahead of time and know they've aligned lifted vehicles before. The guy I took mine to I got there and he googled in front of me how to do an alignment on a lifted vehicle... I ended up being there for 3 hours

 

can getting an alignment fix DW?

 

If it's out of alignment then yes.

 

Would also check all bushings in your suspension to make sure they aren't deteriorated

 

to check ball joints, jack up one side of your front end and see if you can move the wheel in any way other than back and fourth. Also i fixed my death wobble issue by replacing my steering stabilizer and using a larger bolt on my track bar
had to drill out the bushing a little)
