Need some ideas

So here is the lay down. Just bought the Re-speed bushing kit. Installation went great and everything. Couldn't wait to drive it. So then the problems start. Get it on the road and I start hearing a grinding noise from the rear. So I kept screwing with it hoping it was just needing some break in. Then I come to realize that the only time its making the noise is when I'm turning right. Ah I also just did the shoes on the rear drums while it was up in the air. Part of me wants to believe its the watts link binding.

Anyone have any ideas?

jack up the car and look for spots where it was rubbing, is the car lowered? if you have someone to help you.. put the rear end on stands and bounce the car while watching the suspention, if you find nothing pull the brake drums and check that every thing is ok

It's sitting on respeed springs but its about stock height. It's more of a rotational noise rather than a constant grind. I can't find any spots where its rubbing and considering i painted all the arms while I had it apart I figure I'd at least see spots if it were.

Yes that is correct, sounds like it's time to pull the brake drums and check that everything is ok.

Yeah I've got suspicions that the drum isn't fully seated properly. I kicked the tire for giggles last night and i kept hearing something that I'm assuming was the outter drum grinding about. Not cool.

When you did the final tightening on those bushings, was the weight of the car on the wheels? If you tighten them with the suspension hanging, you can run into all kinds of strange issues...

Actually really glad you jumped in on this tetsu. I've checked the brakes about 3 times now and can't find anything. As for the tightening of the bolts etc. I did some reading through about 10 pages of watts link search and found some stuff on that. So the first time I did it with the axle hanging and then I pulled it up on some roll on ramps to keep the pressure on the rear and undid all the fittings and reseated them. It helped but I'm still hearing the grind, its just not as bad sounding. So really quick just to go over everything, I redid the rear end minus the upper control arms with polyurethane bushings per the re-speed kit, pulled the rear sway bar, replaced the brake shoes (i hate our drums). I'm sitting on tokiko blues all around and respeed race kit springs all around.

Finally getting back to this. Its definitely the rear driver. I'm still thinking it's got something to do with the brakes, still not 100% though. I'm thinking it might just be easier to just pick up a gsl axle w/ lsd and disks and be done with it. I'm meaning to get one any way so anyone got one for sale?

Upgrading to a LSD rear end is an excellent upgrade. Nevermind the joy of never having to work on drum brakes again, the limited slip is a heck of a lot of fun.

If you are only hearing it on the turns it cannot be breaks right? Those shouldn't be taking any sort of side load, unless you have really messed up the reinstall. To me it sounds like you didn't dog down a bolt all the way and something is sliding and scraping on the turns. Might sound stupid, but to a really thorough search for a loose/missing nut, even on things you didn't think you disassembled. It can be really easy to forget a part, and some of them are particularly hard to see from an exterior angle, so move around a bit as you look.
