Here is my experience and heed my words! If you want pain and sorrow follow my experience. If you want a more pleasurable experience follow what Eddie has said over and over again and again in many a thread and write up. I have slightly different angles and lengths of drive shafts because of the V8 conversion. Tom Woods front and rear also went from 5.13's to 4.10's but probably should have only gone back to 4.88's. Same issues and after getting rear happy, just a small vibe to fix from rear, went to front. The front was WAY out of balance but this just narrowed the RPM spectrum of the vibe. Started at 4.5 degrees and worked my way down one turn on lower arms at a time to just above zero on caster. Now what? Bump steer is terrible! So I turned the C's, gusseted the C's and trussed the axle. Now if I would have listened and saved for the Pro Rock I wouldn't have a 30, wouldn't have wasted all the time modifying it and wasted money on parts I can barely recoup cents on the dollar for! You know the saying real world higher education is expensive and yes it is! Point being every change you make causes 2 more problems which lead to 4 to 8 on and on so you need to stop the cycle before this happens. Knowing what I know now I would have gone the different axle route and probably a different aftermarket DS. Its great you guys are asking questions its the listening I have found personally, myself, that can be lacking. Food for thought I guess! Good Luck!
P.S. Some may be wondering if all this worked out? Yes it did but two wrongs don't make a right!
