Manual Steering Box Leaking - Question

[estoltman]

I don't want to rebuild it or buy a rebuilt one. Why? I'm planning on doing the FJ60 PS steering conversion, but didn't want to do it just yet.

I can keep filling it with gear oil. I also read that some folks were putting in additives or packing with grease.

Are the rebuild kits still available? I read that some of the parts were discontinued.

Pump it full of grease. Offset the 90wt out through the leak. There is nothing happening in that manual gear box that grease won’t work for

Interesting - found this article recommending lithium grease in Saginaw gear boxes. Saginaw Manual Steering Gear Tech Tip #1. Gear oil or Grease. Which to use? - Midwest Steering - https://www.midweststeering.com/saginaw-manual-steering-gear-tech-tip-1-gear-oil-or-grease-which-to-use/#:~:text=Our%20advice%E2%80%93Use%20LITHIUM%20GREASE.

I need to do the same thing as OP. What brand of grease and how full do I fill the gear box?

I asked the same question a week ago and got a dozen people telling me to pack it with grease.
I plan to find a grease nipple that fits the thread of the filler cap - haven't tried yet, and might need an adapter, but pumping in grease from the top through a nipple, and blowing out the oil at the bottom sounds like the easiest route to me.

Same issue during my current rebuild. Cruiser parts LLC has a gasket kit for the manual gear box. However I’d really like to find a rebuild kit. Does anyone know a vendor who carries one, everything I find is for PS not manual….

 

[estoltman]

I understand the rebuild kit is discontinued. I ordered the 3 parts below, a gasket and 2 seals, from toyotapartsdeal.com. There is also a shim that goes on one end. These are also available in different thickness. I did not order one because I'm hoping the current one will work and if I need a different one, won't know until I measure.

Parts:

	Part Description	Price	Qty.	Subtotal
	Part No.: 90311-18010SEAL, TYPE T OIL	$5.28	1	$5.28
	Part No.: 90310-32024SEAL, TYPE S OILReplaced by: 90311-32014	$8.88	1	$8.88
	Part No.: 45332-36010GASKET, SECTOR SHAFT	$1.95	1	$1.95

My breather valve was also damaged, but ordered that from somewhere else. Toyotapartsdeal.com has those as well: 90930-03058

Shims, Gear Housing End Cover. PN# 45323-36010 thru -36080. 8 diff thicknesses.

There are also 2 bearings you can get, but they are $59.00 each. Doubt they go bad and can probably replace with a generic one.

There is a replacement worm gear assembly available as well for $99. I would use the service manual and check your current one before replacing.

Here's a video on rebuilding one; don't use gasket adhesive to act as a shim as he does, though.

Here's another:

I did the same as estoltman and replaced the two seals and gasket from Toyota Parts Deal.

However, I made the mistake of totally disassembling before referencing any guides. I removed the balls and all. Big mistake. “THIS” thread and it’s video link saved me.

Thank you guys so much! The “After” image is very motivating lol

finally received my seals for the steering box.

In the meantime I removed my body mount bolts, wrench, cutting wheel, sawzall and discovered I need to replace 2 of the mount on the tub. It’s easy to find the frame side body mounts but I’m having a difficult time sourcing what I need for the tub side. Specially for my 79 it’s the two driver and passenger which suit just before the rear wheels. They are toast….. I also need my wheel well braces that was an easy find. The rear corner frame braces and really the list goes on. Gas tank skid, gas tank, few frame mounts. Most of this super easy to find but those tub side mounts are proving difficult. Any assistance would be incredibly

Or will I simply need to make this bracket myself?

Mine was rebuilt by Mark @65swb45
It’s been filled with the correct fluid and perfect ever since
