FJ07/4Runner85
New Member
I have a 85 4Runner that jerks as I am cruising in 4th gear or higher. I have had various things done to fix this will little help. My last thought that was purposed was a SPIDER GEAR replacement in the rear differential? Any suggestions? Also its gutless which I have accepted for a 31 year old 4 cylinder but I have had a new head installed that helps some.
