1995 Ford Explorer Making Noise - Chassis, Suspension & Steering
Question: All movable joints in my front suspension are making a horrible squeaking noise. The joints are sealed thus they cannot be lubricated; however, the tie-rod ends do have boots but no grease fittings. Is there a way to grease these joints? Should I use a needle to inject grease into the boots?

Technican: Hi,
You can inject grease with a needle into the boots. However, after your squeaking noise has started, it most likely is too late. The parts have worn so that it is now metal rubbing metal and should be replaced. Again, you most likely do not need to change everything. Maybe 1 or 2 parts are making all the noise.
Owner: Only the tie-rod ends have boots. The ball joints and control arm bushings/joints do not have boots. Is there any way to lube the joints that do not have boots?
Technican: There is no practical way to do that.
Owner: OK, so what is the impractical method?
Technican: Drill a hole in the steel case, thread it, install a grease fitting and pack it full.
Owner: Yes, that is impractical but may be do-able. I will have to check whether there is sufficient clearance to drill without removing the joints from there mounts. OR, did you intend this as a joke? :)
Technican: That is the only possible way to lubricate it. It is not practical. If there is any play in the joint, IT NEEDS TO BE REPLACED. If a new joint is kept lubricated, it will last a very long time.
Owner: You are obviously assuming that a new joint will have a grease fitting; otherwise, how can one keep it lubricated?
Technican: Most new joints do not have fittings. I was speaking from a design point of view. In real life, if the joint is bad, change it with a good quality joint and you will need to do it only time every 5-10 years. Here's How To Get Guaranteed Solutions In Minutes
