I put in my driveshaft last week and was amazed at the throttle response difference from the stocker vs. the FRPP Aluminum one. But while my friend and myself were underneath my car tightening up the bolts, one side of the dog bone was loose and sliding up and down the bolt it is on pretty easily. My questions are; Can the dogbone come off? Will there be any problems with vibrations or excessive noise? With Steeda LCA's can I unbolt the quad shocks when I install them? They are the Steel HD ones that I picked up brand new at cost from a Steeda distributor, or should I sell them and go with an upper/lower combo from UPR or the XD's from MM?
You probably could have lost the dogbone long ago. With FRPP 3.73s and an alum ds, it shouldn't be any problem at all. Since you have the steedas in hand, just keep them and install them. Yeah, you can remove the quad shocks, most people do, but I would keep them on.
As long as the Steedas aren't urethane on both ends (you need a spherical/delrin bushing), you can take the quads off.
Nope, they are just the Steel HD's, I believe they come with Poly ends, part number 555-4421 Steeda Steel Lower Rear Control Arms - '79-'04 Ford Mustang
