I have been trying to resolve a pretty bad shake at 55 mph+ speeds. It is not so much a shimmy but a full on shake. Pumping fresh grease in drive shafts didn't help. Prying on U joints didn't reveal anything. CV axles are not leaking or seeping, they don't make any grinding or clicking or popping noise at any speeds.
So I ordered these parts from local Toyota dealership before even getting under the truck:
Drive Shaft
Front: 37140-60370 $259
Rear: 37110-6A610 $346
CV Axles: 43430-60040 $401
Total about $1500
Plan of action was to disconnect the front shaft and take off the front hub flanges to see if it would eliminate the shake. If it doesn't then remove the rear drive shaft would help.
But guess what? The driver side wheel has a large amount of play in it from the inner tie rod!! Like a really big, unsafe play when you grab the wheel at 3 and 9 o clock! and the steering rack boot is full of power steering fluid
So before anything else, I am planning to buy a tie rod kit from
@cruiseroutfit and replace the tie rods to see if that addresses the shake. And then dump some AT 205 in the power steering reservoir to deal with the leak.
Or I could just replace the whole rack be done with it. Will need to get an alignment either way.
