mpanzar Posted September 3, 2019 Share Posted September 3, 2019 (edited) My steering gear box has a lot of play in it. After I pulled the gear box I noticed that the previous owner installed a re-manufactured one. When I browse rockauto it seems the box I currently have is for ½ ton chassis. I was under the impression my 1986 18ft sunrader (model No. RN55L-KRTEA3W) was on a 1 ton chassis. The gear box is mounted using 3 bolts, 2 horizontal and 1 vertical which I believe implies it’s the RWD type. There is a 1 ton option on rockauto that uses the same (or very similar) bolt hole pattern. Can anyone provide some insight? Id like to replace it with the true 1 ton option if that’s what it came with. This is the one that came of my sunrader: this is the gearbox i believe I have on rockauto but it says it excludes the 1 ton.... https://www.rockauto.com/en/catalog/toyota,1986,pickup,2.4l+l4,1277401,steering,steering+gear,7416 Here is the 1 ton from rockauto: https://www.rockauto.com/en/moreinfo.php?pk=3024168&cc=1277401&jsn=10427 When i search ToyotaPartsDeal.com they reference this one, and its definitely not what came of the sunrader. 44110-35070 https://www.rockauto.com/en/moreinfo.php?pk=31315&jsn=10445 Edited September 3, 2019 by mpanzar Quote Link to comment Share on other sites More sharing options...

Maineah Posted September 4, 2019 Share Posted September 4, 2019 How many bolts on your front wheel? Quote Link to comment Share on other sites More sharing options...
Michael Panzarella Posted September 5, 2019 Share Posted September 5, 2019 It originally had the 5 lug (non dually) front hubs. Quote Link to comment Share on other sites More sharing options...
mpanzar Posted September 5, 2019 Author Share Posted September 5, 2019 I need to delete that account ^^^! Anywho, 5 lugs. I just looked at another sunrader, 1987 21ft and it has the same gear box... so maybe the 1/2 is fine? or rockauto is wrong? Quote Link to comment Share on other sites More sharing options...
Gulfstream Greg Posted September 5, 2019 Share Posted September 5, 2019 Yup, 1/2 ton chassis. Not to say a different box can't be stuck in it. Google for some toyota 4x4 pickup rock crawler parts. Quote Link to comment Share on other sites More sharing options...
tstockma Posted September 14, 2019 Share Posted September 14, 2019 (edited) If your steering box is loose, traditional design says one of those bolts is actually an adjustor, and you can tighten it up. Work the level a bit as you tighten it to keep it from binding, and leave just a little play. Myself, I wouldn't worry about the 1/2 vs 1 ton box, you're probably not putting your rig thru the rough terrain the 1 ton pickups would be going thru. Old chevy trick from the old days....when the rubber seals wear out so you're leaking, drain it & pack it with wheel bearing grease. Thickness of the grease prevents it from leaking near as bad & it adds a bit of smoothness to the steering, at least in my old '61 Corvair it did... I seem to recall adding a grease nipple ("zerk" fitting) to the box on the bottom somewhere, give it a few pumps every time I greased ball joints & tie rods to keep flushing grease thru. But my advice is, if you can find the tightening bolt, keep that current box. DOH in fact I think I see it on your picture above - that Rock Auto photo - towards the top - and it looks like a slotted, flat screw head, with a lock nut. I see it in one of your photos of yours too. At least that's a possibility. Edited September 14, 2019 by tstockma Quote Link to comment Share on other sites More sharing options...
Maineah Posted September 15, 2019 Share Posted September 15, 2019 Be sure the steering arm is the same length! Knew guy that replaced the steering damper jumped in and promptly crashed into a wall because the damper bottomed out and cut his steering radiance 50%!
