alignment/tire wear problems
« on: May 10, 2005, 10:07:56 PM »
I have a 94 ext cab with s.a.s.,hy steer,landcruiser rotors/v6 calipers. My tires started wearing funny so a friend and I aligned it using the ol measuring tape method.Seemed ok until I got to around 30 or so then it started the "Death Wobble".I checked the wheel bearings and they were fine yet the tires seemed to lean inwards.My rims are 15 x 14 with 36's.Could my knuckle bearings be shot or my rims too wide or both? You think the tires just have a bad wear pattern?Somebody help cuz my tires are going fast!!!
I'd rather push a Toyota than drive a Jeep!!!

My 85 runner's front tire leans inward also.  I cannot figure out what it is even after completely rebuilding the front axle i.e. bearing, trunion bearings, seals etc...  I have marlin crossover with 15x10, 35" toyo's.  Let me know if you figure it out.

How is your steerind stabilizer?  Lots of times that can cause a wobble at a certain medium speed.  As far as tire wear, what kind of irregular tire wear are you getting?  I would defiantly check your trunnion bearings and if they do need to be replaced replace them with genuine Toyota.  Do not use the cheep replacements (they have a steep angle to the bearing and race)  As far as the 14" wide wheels I really dont know if that would contribute to any of your problems or not but I would ditch them anyway unless your tires are 19.5" wide.

Its not surprising to have a bent axle,,,they do bend....also  unbalanced tires cause death wobble..did you throw a weight?

wheels with too much offset magnify any issues you have with any loosness in the steering components.  One thing to check is your castor angle.  I had some pretty bad deathwebble and I ended up putting 3" shims in the front and its totally gone now.  If your castor angle is too high then when you aloign the front end you actually are tipping the tires a bit.  You need to set toe perpendicular to the trunion bearings, not straight ahead of the housing...
Full hydro, 186:1 with an auto and 44's what could go wrong??
