Re: 1964 C10 fleet side swb
I've been having that front end pop for a few months now and today I finally found out what it was and fixed it.
When installing the coils springs I was placing the springs in the lower control arm and using that groove in the lower to align them. Problem is the top does not fit in the D shape properly when this is done, found online that someone recommended starting on the upper since it is a fixed position as well and it doesn't move like the lower control arm when you are installing. I found the third ring down on the coil spring was rubbing the engine cross member where it goes up in there. The spring would also rotate slightly from the upper portion not being locked into the D shape. I think it would rotate and give a slight gap and I wouldn't hear the popping for a little while and then spin back and start it up again. Simply dropped lower control arm and aligned the upper first then brought the control arm up to the lower side of spring. Did this to both sides and now have a 1" gap or more all the way around the engine member. Took it down the road and no more popping, the spring had been rubbed pretty good on the drivers side and that's were I was hearing the noise most consistently. Also figured out the belt needed for the Holley kit with a little work around. I dropped my idler pulley size under the alternator from a 90mm to a 76mm and the 113" belt fit. Seemed pretty tight to me but the tensioner now lines up with the marks it needs to almost perfectly.
