Re: Check your U-bolts!!!!!
working on the conversion shortly after getting my '91 bluebird, over a period of about a week we would hear these loud bangs. sure enough, it turned out to be the 4 front u bolts. all broke in the same place. a couple of months ago, parked in a buddies driveway overnight, the same bang. this time we knew what it was and got a new ubolt on b4 the rest went again. cut the old one off with a grinder. lucky it's a cheap fix.
