1998 GMC Jimmy
'98 GMC Jimmy,4WD,4.6L. Inside wear on the front tires, irractic steering,
and advice from a tech on an attempt to align the front end, seems I need the ball joints replaced.(approx. 130K on vehicle) Now, on researching the parts on-line, I find info on upper and lowers. Due to the estimate on repair, looks like a job I might have to do myself. 4 yrs auto mechanics a thousand years ago in high school, and a HVAC tech forever, not too bad with a wrench, and the fact that I'll probably own used vehicles for the duration. YES guys, I'm......."thrifty". If anyone can square me away on a few points on the repairs, what to expect, what parts, etc...I already have plenty of headache powders, and band-aids, I would be in your dept......THANX |

I find a 10 lb sledge, better known as a BFH to come in real handy on
ball joint jobs.... I also recommend two or three times daily for a few days before the job to soak everything in a good penetrating oil. That should make the job a bunch easier. At 130K I also think while you have things open, you might want to closely inspect all the tie rod ends as well and address the wheel bearings or hubs if they are re-packable.

As Mike says, one BFH - I find 4 pounds is usually adequate, myself
<g>. Tools: buy or borrow a pickle fork for unseating the ball joints. They also make a smaller size for tie rod ends. These are cheap but many parts stores have a loaner tool program for such things. You may also need spring compressor for the coil springs - seems to me I needed that on a GM car but it's been a while so I may be remembering wrong - and the taller the jacks stands the better as that gives you a better swing with the hammer. I would also second the suggestion to check the tie rod ends and all the other moving parts before you start. With the price of a decent alignment anymore, you might as well replace whatever is questionable and just have the alignment done once.

This isn't too bad of a job if you have the right tools:
1. If the Ball Joints are original, you will need to grind off the rivets. The new Ball Joints will have bolts. I would throw them out and replace them with Grade 5 bolts that won't strip. 2. You will need a Pickle Fork (two sizes are generally best) and a BFH as said above. Also a cold wedge and punch helps when trying to remove the ball joints themselves from the A-arm. 3. You won't have to worry about coil springs thankfully, Jimmys/Blazers use Torsion bars. 4. If you have bearing noise, this would be the time to replace the Hubs. They are a sealed unit with an ABS unit attached. They are also rather pricey (Even on eBay) so I wouldn't touch them if they aren't making noise. Hope this helps. -John |
