If you are on the East side or live in Aurora-there is a shop that can handle correcting the Death Wobble in Jeeps.
Reasonable in price and they test drive the Jeep before alignment and correction and after alignment to verify that the trouble has been corrected.If the first alignment doesnt correct the DW-they will realign it before the Jeep is returned to customer.
They fixed my 93 GC with stock Upcountry suspension --when no other shop could .
