    Engine Diagnostic Help

    Did a compression test today and the results are #1 174 #2 174 #3 174 #4 167 #5 179 #6 159 #7 172 #8 171 I know GM says a 20 psi variance is allowed between cylinders and #5 and #6 are exactly 20psi apart. You guys think this is fine or should I test the cylinders further?

    Ball Joint Replacement

    I have checked e-bay a couple of times with no luck. I have never checked out Rock Auto so I will do that. The only parts store in my area that has the LCA's is Advance Auto and they are $200 each. Plus I have ordered parts from that Advance in the past and they always show up damaged so you...

    Ball Joint Replacement

    Hi everyone, I have a 97 hoe that I bought about 2 years ago. I went to change out the lower ball joints and after fighting with it ( using the proper ball joint tool) I finally got it out. After I removed it I noticed to splines on the lower control arm are mangled and the new joint...
