Information for replacing Power Steering Gear Boot/Bellows is listed below. I found this to be one of the easier maintenance items that can keep away rust problems for inner tie-rod ends and rack gear.

1) Power Steering Gear and Linkage (removal and installation) information begins on page ST-12 in the Field Service Manual (FSM).

2) To maintain current alignment position as close as possible for a driveway job, mark the current alignment position behind the thread bolt on the outer tie-rod end. I used some extra touch-up paint as it dries fast. I plan to get the front and rear wheels aligned ASAP as the rear was recently upgraded with new struts and sway bars.

3) The tie rod end and alignment bolt are both 22mm. I used an open end / box end for both bolts.

4) Remove the outer tie-rod from the inner rod.

Note: The jack in the pictures was for raising the lower arm as part of the lower sway bar end link replacement. .

5) The old boot had started to deteriorate, so I used a linoleum knife to cut away the old boot. I was glad to see the rack doesn’t leak and appears to be in good condition. The ball-joints feel tight, strong, and still well lubricated. I treated the inner ball-joint with some Waterproof Green Grease from Tractor Supply Company. (TSC). Green grease is often used for boat trailer wheel bearings.

Multi-purpose Synthetic Polymer Grease, Industry proven for over thirty years Recommended for cars, trucks, boats, trailers, RV's, 4-wheelers and farm equipment. Outlast regular grease up to 8x. Saves time and money. Seals and protects. Ideal for wet environments. Fertilizer resistant.
Works in extreme heat. Compatible with other greases. Boat trailer wheel bearings. Green grease lasts longer than regular grease and provides superior parts and equipment protection. Exceptional operating temperature range: Green Grease meets or exceeds major manufacturer performance requirements, operating temperature range up to 500 degrees. Tenacious synthetic polymers resist high impact, shock loads, wash-out and centrifugal separation. Special EP compounding helps prevent wear under heavy-duty conditions. Waterproof Green Grease acts as a rust preventative and protects bearings, seals and open gears against costly repairs. Repels fresh and saltwater.

6) Position the rack boot on the inner rod and push it into place. The boot will slide over the inner area lip while the outer boot will snap into a groove.

7) Once the boot is into position, use the wire to wrap the inner groove 2x and twist to tighten. I cut away any excess wire and smooth any sharp ends. to make sure the end will not come into contact with the boot and lead to wear or puncture. Also a small o-ring is included to fit around the smaller boot end.

Great job and documentation, as usual. While that boot is clean and new, hit it with a spray of your favorite rubber protectant, and repeat at every oil change, and it will last much longer!!!!

Be sure to have it aligned ASAP. Alignment is never preserved.

Thanks guys!

I use an old product named Ru-Glyde from NAPA to clean rubber as the glycerol is a vegetable soap then follow up with some Shin Etsu rubber seal preservative. I treated the CV joint boots a couple of weeks ago. There is something about Shin Etsu (Japanese) formula that when I rub it on it makes it almost feel like new again. I think it is also used on personal jet door seals.

Sounds like an OPINION, not a fact...unless you have access to an independant test showing long term results of all the various different brands performance?
