I thought I'd ask here since Stephen probably knows more about 205s than most. Is there any tell-tale signs that a 205 needs rebuilding? I picked up an 89 GMC 1 ton dually (old body style) w/ 112K miles. The Turbo 400 was rebuilt by the previous owner and I will be doing the motor as leakdown tests and fowling plugs tell me it's about time. How do I know if the tranfer case needs work? It was never wheeled hard. Also, if you tell me I should go through it, how difficult is it? I've talked to transmission shops that won't touch 205s due to all the needle berings. Is this something I should tackle myself or leave to the pros? I've never been inside a transmission or transfer case before but I feel confident doing just about any other automotive work. Thanks in advance. Eric M.
