1. Identify the Squeak's Source:
* Pinpoint the Location: Is it coming from the suspension (shocks, struts, control arms, ball joints), steering (tie rod ends, idler arm, pitman arm), or body mounts? Try to isolate it by moving the vehicle (carefully!), jiggling components, and listening closely. A helper can be invaluable here.
* Reproduce the Squeak: What movements trigger the squeak? Turning the wheel? Going over bumps? Braking? This helps narrow down the culprit.
2. Re-evaluate the Greasing Process:
* Correct Grease Fittings: Ensure you're greasing the *correct* fittings. A shop manual (online or physical) will show you the locations of all grease zerks on your Blazer's front end.
* Sufficient Grease: Did you pump enough grease into each fitting until fresh grease appeared? If not, the old, dry grease might still be causing friction. Try greasing again, paying close attention to this. Use a high-quality, multi-purpose grease.
* Zerk Condition: Are the grease fittings themselves damaged or clogged? Replace damaged zerks. A small wire or pick can sometimes clear a clogged one, but if it's badly damaged, replacement is best.
* Boot Integrity: Check the rubber boots protecting ball joints, tie rod ends, etc. Torn boots allow grease to leak out and dirt to get in, leading to squeaks and premature wear. Replace damaged boots.
3. Beyond Greasing:
If greasing doesn't solve it, the squeak is likely from something *not* greaseable:
* Bushings: These rubber components wear out and can squeak. They often need replacement, not greasing. This is a common source of suspension squeaks.
* Sway Bar Bushings/Links: These are relatively easy to replace and a frequent cause of front-end noises.
* Shocks/Struts: Worn shocks or struts can make noise, though usually more of a clunking or thud than a squeak.
* Body Mounts: Rubber mounts that connect the body to the frame can deteriorate and squeak.
* Brake Components: While less likely to squeak continuously, brake pads or calipers can sometimes make noises if worn or sticking.
* Steering Components: Worn tie rod ends or other steering parts can also produce squeaking.
4. Professional Help:
If you can't pinpoint the source or aren't comfortable working on your vehicle, take it to a qualified mechanic. They have the experience and tools to diagnose and fix the problem efficiently.
Important Note: Driving with a squeaking front end that isn't addressed could indicate a serious mechanical issue. Ignoring it could lead to a dangerous situation. Safety should always be your top priority.
