I have a 82 3/4 ton (8600 GVW) burb basically stock. It has the factory 4 front shocks and the steering stablilizer shock. On rare occasion when brake is applied there is a substantial front shimmy with assoc steering wheel shake. First time I thought front wheel might be loose. Only happens occasionally not very often but very pronunced. Tire wear normal tracks and steers normal. Tows normal only happens with braking and then only sometimes.
