Front end "thumping" sound
Please excuse the long write up. I want to ensure you have all the info.
I have put in new ball joints about 10-15K ago. After I returned from my deployment, I noticed a thumping noise in the front end of my truck when I went over bumps. I had the front end inspected and replaced inner and outer tie rods and idler arm. When I had the allignment done, I had a different tire shop do an inspection on the truck and they said the front end suspention looks great.
The stearing wheel was pretty loose when I started, but tightened up a little bit after I replaced the parts and had an allignment. It's still a little sloppy but it's a truck and I plan to have the intermediate drive shaft inspected.
In the process of all this, I looked at the lower A Arm and it looks as though the bump stop is contacting it on a regular basis. I is creal where as the rest of the A Arm has typical dirt and dust. I'm assuming this is my thumping noise by the front tires. Any suggestions would be appreciated on a culprit. The only thought I have is the Torsion Springs need to be adjusted, if that's a typical adjust ment that needs to be made. Thanks in advance for your help.
