RC 2.5" lift vibe issues and oil leak

So my problem is I had the RC 2.5" lift installed on my 05 TJ for about a year no t case drop in it had slight vibes but it didn't seem too alarming. About 2 months ago I noticed there were what seemed to be oil stains on the flares, rear bumper, and undercarriage of my jeep. had to change the rear pinion seal because it was leaking. 1 month ago put in a .75" spacer up front to level out, had slight vibes around 35-50mph so i put a 1" t case drop hoping it would solve things. Only noticed vibes at around 45-50 after. Now I am getting vibes at those same speeds when I am accelerating and when I let off the gas which seems to occur from about 40 down to 20mph. It makes a grinding noise. and i noticed that there are stains on the fenders and bumper again. what should i do?

Have you tires balanced first just to rule out they are not the cause, then I would take it to a drive line shop and see if they can figure out where it is coming from. Or start testing things maybe take out the front drive shaft to eliminate that as being the cause.

I looked under my jeep today and it doesn't look like either the front or rear pinion seals are leaking. I did notice though there looks like what seems to be scratch marks on the front drive shaft where the auto tranny skid plate is. Could removing the skid plate possibly make some of the vibes go away? I am not going to be wheeling much until I get a motor mount lift anyway so I am not really worried about the transmission scraping against anything. Would it be unwise to remove the transmission skid plate and just leave the t case skid? Not sure if it really supports the tranny.
