Front end wheel knock.

sounds like a CV joint to me !

people who post questions , receive suggested solutions and go away REALLY SUCK !!!!!! people like you lesan !

No, everything is tight. I replaced the front engine mount, it was worn. I'm going to go for new struts and springs.

I'm still here. However, I'm not chained to my computer.

I don't think struts and springs are the problem.

Jack the car up. Do the springs rattle when you shake them up and down? No? It's NOT springs.

Struts? I can only see them making a noise if something is obviously loose, like the bolts at the top.

Torque every bolt in the front end to factory spec. That means loosen it a bit, and then torque it with a torque wrench (I'd really like to have a wrench that's a torque wrench when tightening, and a normal wrench when loosening.)

Find a place you can reproduce the problem. Have a buddy with good ears (no rock band fanatics) stand outside the car as you go by. Make sure it's coming from where you think it is. Have them stand on both sides of the car as you go by.

Don't throw parts, labor, and money at the problem, find the problem.

One more thing: Check the wheel bearings. Jack the front end up. Rock the top of the tire left, the bottom right, and vice versa. Compare it to the silent left side. If there's more than the very slightest play (there should be just a lttle, just a bit above the threashold of tactile detection), you have a loose bearing. The first thing I'd do is retorque it to factory spec.

I've had 2 mechanics go over the entire front end, removed, inspected and replaced (with same assembly) the right side strut assembly, but can't isolate the problem. The suspension is 6 years old, and I'm only paying cost for the parts, no labour charge. Less than $200.00 for everything. It can't hurt. I trust it will fix the problem.

Thanks. Leo

PS: Checked the bearings, all the linkage. Everything is snug. It only happens at very low speeds. I can run over a cow at 60 mph and not feel it.

Thanks. Leo

Couple of things.

Loose wheel or incorrectly installed wheel. Clean hub and torque the wheel nuts.

Outer CV shaft joint is moving in joint because the clip has come loose or missing.

Disk Brake pads moving inside the calliper. Had that problem with a Ford Focus. The aftermarket pads backing plate was too large and when I went over a bump or accelerated/slowed I would get a knock. I was sure it was a drive shaft but after grinding a little off of the backing plates of the front pads the knock was gone.

Tomorrow I'm taking it into the shop again, we'll start with new struts and check every nut and bolt within the suspension system again. I checked the brakes last Sat., they were fine. I'll let you all know.

Thanks everyone. Leo

The struts were finished, especially the right side. New one's made a big difference. There's still a slight knock which are likely the sway bushings. I'm changing them this Fri. Hope that's it.

Be well.

OK. Here's the score so far; changed the stabilizer links, put in new struts and new sway bar bushings. The ride is about 85%, still has a slight thump at low speeds. Maybe it's normal for a 6 year old Sentra. I'm used to a Nissan pick-up which I've driven for the past 14 years, rode as smooth as silk, but then it's a ladder frame, everything is isolated from the body.

Could be I'm not used to uni-bodies.

Thanks again everyone. Leo
