I think its really because the upper trunnion really isn't a problem part. I dunno why people are afraid of them. They're weird, but so what (we drive Ramblers). Even if you have bad trunion, ruined caps and ruined upper arms, the expense of finding replacements is always far less than fabrication. And it works first time. Data point: I have not heard of a trunnion problem that was not related to poor maintenance (usualy previous owners, eg. used-car-syndrome). Data point: Balljoints wear out all the time and you get lots of crap out of today's aftermarket. Data point: I personally have never seen an upper trunnion wear out when it was properly maintained which consists merely of greasing it annually (TSM says 30K!). They last forever. I just scored a 1964 Ambassador upper with needle bearings that WAS well-maintained. Fresh grease! It looks like new inside and if the ones in my 63 Classic ever wear out (old, sleeve bearing, 325K miles) I now have replacements into the *next* century. Racers already have all those nice coil-over setups and all that. They just cost too much for street use. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
