Hello,
Demonstrating my lastest modification accomplished to a 1982 FJ43 I’m restoring.
Back ground:
Factory power steering that I modified to delete the drag links and upgrade to a more modern steering system with a combination of factory Toyota parts...namely an FJ80 power steering gearbox whose modification is well documented in other forums by other members.
Problem:
The upgrade to the FJ80 gear box required the deletion of the OME SD23 steering stabilizer due to the geometry and travel limitations of the SD23. The SD23 only provided 454mm extended to 316mm collapsed travel range with the 454mm not being long enough for full left turn. An SD24 from an FJ60 would not allow enough collapse at 417mm and thus unable to turn wheel fully to the right. Geometry on modification drove a steering range of 315mm collapsed to about 470mm of travel stop to stop.
Objective:
Reintroduce a steering stabilizer using factory available parts.
Ingredients required:
FJ80 power steering gear box installed per previous posts
FJ70 LHD tie rod and relay rod end kit
FJ60 relay rod, unmodified
FJ60 tie rod end with each end cut short about 1.5” and re-tapped using...
M23x1.5 LH and RH thread tap
OMESD40 steering stabilizer with 499mm to 310mm travel.
Dorman 918-305 power steering oil cooler
Big ass wrench to tap
Solution was combination of above parts with pictures attached. Hoping to get the rest of the vehicle finished this winter to ops test the modification. So far this modification allows full stop to stop turn and normal geometry of the stabilizer, pitman arm, et al.
