[Fot] TR CHASSIS FATIGUE - A CAUTIONARY TALE

[Bud R]

I had exactly that happen to my TR6 on the way back from VTR2007 at  
Valley Forge. Ripped a piece right out of the cross member. Lucky to  
make it home. I welded the piece back and went back to my old lever  
arm Armstrongs rebuilt by Apple Hyd. to heavy duty. I think the  
mistake I made was not adjusting the bump stops so they would engage  
before the shock reached its limit. Once that happens it looks for the  
weak spot which seems to be that cross member. If I go back to the  
tube shocks I'll weld a 1 inch piece of square stock up in the cross  
member so that it becomes four sided instead of the stock three.
