I have an 87 4Runner turbo that is having a death wobble around 15-25 mph. The intermediate shaft had been removed and or adjusted by the previous owner due to a SAS and steering box relocation which over extended it. The rag joint is bad I think which might be the culprit. I’m looking for measurements of how much spline should be showing on the firewall side to start and how far back the steering box is from the frame to try to fix.
