Theory on preventing frame cracks around steering box and panhard bracket (3 Viewers)

[Kernal]

@SNLC said "Toyota fixed this problem when they added coil springs to the front of the 70-series in 1999 --- you have to remove the front frame cross-member and replace it with the 70-series."

Not planning to do that mod myself, just wondering how the 70 Series updated design is different from the 80 Series?

Anyone have photos showing the difference ie: for comparison 70 Series vs 80 Series?

I plan to leave well enough alone unless an issue occurs.

Wow I do not know how you guys were able to strip and grind the paint from inside the frame rail.

During the repair Lee turned to me and asked “do you hear that? Sounds like something is boiling.”

Giving how my steering is responding after the repair I’d say it was my power steering fluid.

The power steering hose has an U shaped metal pipe with a metal mount that bolts to the frame just in front of the steering box. My thought is that there was enough heat transfer during the repair to affect the fluid in the hose.

I’m driving home and will dig into it once there.

As a precaution I’m advising anyone doing this repair in frame, un bolt that hose and tie it off out of harms way.
