2005 VGRS Steering Rack Bushing Replacement with New, hopefully factory identical rubber bushings. Ordered from Bestparts on
eBay after reading these are what rack rebuilders use. They seemed the least chinese? option i could find aside from poly bushings. Really did not want the stiffness of poly on my LX470.
Went into it expecting removal to be a huge pain, and re-installation to be easy and ended up having more trouble with re-installation.
Started by removing both tie rods from the knuckle and unbolting the rack. I left the steering shaft and lines connected. There is very little flex or room for movement, especially on the driver side with the oil cooler housing and filter literally directly on top of the mount.
The bottom bushes are easy, just peel the lip back, work it down all around the edge, and i was able to hit it at a downwards angle with the air hammer which just slides them right out. The upper was a bit trickier, on the passenger side upper, there's tons of room above the rack and i was able to air hammer after painstakingly peeling up the lip, but on the driver side one with the the oil filter housing, i had to hammer the bush from the inside upwards at a difficult angle to get the rack into. Still it took 2 hours max.
During re-installation, i figured i'd just use the factory bolt, a big nut and pull them in, but the exterior of the bush sits lower than the rubber and interior sleeve, so i ended up just compressing the centers of the bush together and it wouldn't seat. I ended up cutting a piece of tube as a shim that fit around the edges but not the rubber, and using a longer bolt, sandwiched the two bushes together and they seated properly.
Huge Improvement, wow. Wheel feedback was really high before, now it's almost nothing. Turns feel crisp and in control now, before sometimes it felt like you had to lean into the wheel extra at the end of the turn to get the truck where you wanted it.
Pulled my rack boots back to inspect how much fluid was leaking out of them, and mud grease water squirted out all over. s***! Ended up pulling off both sides and finding trapped mud water in my boots that had been up against my rack seals for potentially weeks! Got it all really good and cleaned up, rack ends re-greased, torn boots cleaned up, and wrapped the boots in plastic wrap so they would stay sealed while the new ones get delivered. Anyone have an opinion on using oem clamps vs hose clamps on the rack boot? Hose clamps get tighter for sure, but are wider and could could split the rubber
total cost 50 bucks for bushings, 60 bucks for the boots. Mine had very small tears that were hard to find on the edges.
