KingPin bearing JB43 instant failure was created by londonjimny

Hi.

Changed my king pin bearings due to grease leaks and death wobble. All went well and drove fine for 100miles. The wobble has returned as well as the grunt vibration from low power acceleration.

What did i do wrong ?

My guess are that the bearing grease i used wasn’t upto scratch or the shaft seals had gone as i know i haven’t changed them.

Maybe the bearings weren't the only defect???

I don't see you destroying a set of bearings that don't continuously rotate in a hundred miles, not even if you installed them dry.

Many people don't know what "death wobble" is and have never experienced it, it's just something they've heard about, many people don't understand what causes it and king pin bearings are just one of the possible causes.
