Hey all! Wait till you hear this one! I got a "squirrel flat", the other day, and that's what led me up to my rear suspension condition. It went like this- Tooling down the dirt road on my way to the pavement, just before the end, a big red squirrel ran under the middle of the car and I felt it bump under the right rear. After I turned onto the pavement the car started acting "squirrelly"(pun intended?) around the next corner. Drove up next side road and after unloading all my tools, which were considerable, I finally got car jacked up and half-flat spare on, I looked at the tire and it threadbare on the very inside of the tire, all way around, with a hole I could have shoved a pencil thru! That squirrels teeth, I'm sure gave me that flat! Well, anyway, after reverse course and making it to the tire shop, for a new tire(s), I found out that BOTH back tires are severely worn on the inside, with the pass side being the worst. The toe rods seem good and I got new trailing arms and used "knee" sets for both sides online, but the outer-upper control arm bushings are not very good. Dried n cracked. My question is-(finally), being that the lower control arm and the rest of the knuckle bushing are good, if, after I change out the upper control arm bushings, would it be worth it to drill and add grease zirts to knuckle ball joints? Even thru the knuckle housing itself, for the lower arm? It's the hard, expensive one?
