Well, I finally have time/money/weather to chase the pulsing vibration/shaking I have.
First things first was jacking up the front end and wiggling things. The front wheels had lateral play and we decided that it was the wheel bearings.
Upon disassembly, it was apparent that they had been repacked a couple times, but they needed to be replaced a long time ago. The discoloration of the bearings, the major cupping and scoring on the races, and the flat spots on the roller bearings confirmed this. Whoever did the 60k (230k) service (Lexus of Memphis arrrrrrgh) was extremely lazy.
I also finally decided to do something about my CV with the missing clamp. NAPA had a great deal going on, so I bought two of their CVs. The snap ring AND hub flange fit perfectly with no play, so I decided to just replace the one. I have the other NAPA one as a spare and I'll just reboot the OEM CV as a spare. Time well tell if the NAPA axle is any good (I've read all the threads, trust me, I know).
NAPA also carries Koyo (Japanese made) bearings with their Altrom part number. I didn't believe it until I went to the store and four blue Koyo boxes were presented to me.
Getting the lower ball joint out was a BEAR. It would not come out of the spindle. Took a torch, two sledges, and a good 3 hours to free it. Replaced with a Sankei-555 lower joint.
Shout out to Principle Toyota of Memphis for having their parts guy dig thru the all the technician's old parts bins trying to find me a nut I could destroy getting the lower ball joint out. Huge help!
I also discovered that my splines on my rear driveshaft are very worn. Surprising and disappointing. Stuffed it full of moly grease again to see how much longer I can make it last.
I also determined that my front AHC lower shock bushings are shot. Just in awful shape. Will be replacing here in the next month or so.
