If it's a fluid filled hub, yes.
You need to find the leak and fix it. Can be a hose clamp, can be a seal on the servo pump.
IF you have rear wheel drive it may be a grease seal for the rear differential. Otherwise it is probably a wheel cylinder. Check your brake fluid level. GEt this fixed ASAP- Safety concern. Wheel cylinder, brake fluid.. If it's a rear wheel drive vehicle, it may be the axle seal leaking as well. Hello... hello...
Probably brake fluid, your caliper seal may have gone bad
You'll see either fluid or grease leaking out of it.
Hub seal is leaking
You have to pull the entire axle. Take off the tire and wheel hub. unbolt the tie rod from the wheel hub. unbolt strut assembly from wheel hub. Pull transaxle drain plug to empty as much fluid as possible. Use a pry bar to remove the right side drive shaft from the transaxle. Note that some fluid will still leak, despite having drained the transaxle. use a screwdriver to remove the old seal. Moisten new seal with fresh transaxle fluid prior to installing. Install new seal with a seal installer tool and mallet, by gently tapping it into place. Reinstall axle by following steps in reverse order. Don't forget to replenish transaxle fluid with SPIII fluid!
Whatever seal the fluid is coming out.
how do i replace a wheel seal
Okay.... so you have a spindle which is attached to the axle... this is what the wheel actually mounts on. Within that spindle are several components, of which the most important to note are the two bearings (and corresponding races). Now, bearings roll, and thus, they need to be lubricated. This is done with gear oil. The wheel seal at the back of the bearing keeps the gear oil in the spindle.
Internal seal in the Rack & Pinion steering. You probably shouldn't drive it until you get it fixed.
A camshaft seal keeps engine oil in and dirt/water out.
The seal is designed to have a point contact between the O-ring and sealing .... This was blamed on a failed O-ring seal. The escaping high temperature gas ...
