This “friend” of mine was tearing down the front suspension of his 67 GS to do a complete bushing replacement. After the spindles and springs were removed he noticed that he could easily get to the upper A-arm bolts by pushing the A-arm up. Of course he didn’t know the bolts were knurled and pressed in bolts. His 3/8” impact had no effect so he upgraded and used the ½” impact… and they came right out. No problem. In fact they spun so fast that the knurling on the bolt acted like a file and opened those holes right up. Afterwards, I (I mean he) couldn’t figure out why Buick would spend the time and money to put them fancy knurls on them bolts when all then needed to do wad secure the upper A-arm… Till I (I mean he) was putting everything back together.:error: OK now what do I do? I figure the only alternative I have is to weld them in place. Thanks,
Ive aligned many cars where the bolts werent pressed in anymore. The bolt would spin in the hole. In those situations, I would have to get my buddy in the next bay to get in there with a rachet and a long extension and hold the bolt while I wrenched it. Once its tight, it isnt going anywhere. Be careful about welding them in. Sometimes you need to remove these bolts with the engine in place. The exhaust manifolds will interfere with the installation if they're welded in.
Hey Skyhalk, Tell me how to order them, and do you think they will stay in place? I guess others have done the same thing... I don't feel so stupid now. Thanks guys!
It seems like , in the back of my mind, that some body makes some over size ones for cars that had wreck damage.... dont weld on the bolts if you can help it.... they are special heat treated items that will break if you destroy the heat treating.... try this, find a thick washer that the bolt will press fit into and then weld the washer to the frame with a tig.... use the least amount of heat to get the job done....
What he said. Just put the bolt in place and stick a ratchet/extension/socket on there and hold it while you tighten it up. Bert
