Y33 ABS Sensor Question

[KingKarl]

Do the metal casingings of the Y33 ABS sensors serve to ground them? The reason I ask is that I wonder if a small amount of anti-seize lubricant or dielectric grease can be used to keep them from freezing in their mounts on the lower castings of the struts?

I checked the FSM ground dist. chart and was able to find the ABS control unit info but not the sensor. Admittedly, there is an overwhelming degree of probability that I can't read the chart correctly and at least a 50/50 chance that I can't read it at all.

Anyone that cares to share will be added to my will, with the exceptions of Q45Tech, Max and Wes, who are already there.

Hi There:

I just replaced one of my front ones because I damaged it trying to remove it to install my front strut cartridges. I used some anti-seize smeared in the mounting hole, bolted it up and everything works fine. When I inspected the damaged sensor, there are just two wires running to the magnet sensor. Mine broke off while I was carefully prying it out, which cut the connection.

So far, 500 miles and no problems.

Good luck!

Thanks Ted. You had offered help previously when I was trying to get mine out without causing catastrophic damage. I was obviously unable to do so but would really like to avoid this situation in the future.

The whole suspension refurb. project turned into an expensive ordeal with lots of surprises because I was unable to verify a certain part of the maitenance/service history of the car. When I was test driving it prior to purchase 4 years ago, the previous owner remarked that he had just had the front end "done." When I asked "by who" he said "by the Infiniti Dealer." NOT!

Whoever did the job had an unhealthy fixation on the use of the pneumatic impact wrench. So much so that I broke two 1/2 inch drive, 17 mm sockets and a 1/2 inch breaker bar (all "lifetime warranty" tools) removing the strut/stabilizer bar links and tension rods. Also, the strut in the worst shape, as well the Tension Rod bushings were "aftermarket" junk that had failed miserably in the 40k miles that I had driven the Q. But thanks to IOS and job security, I'll soon be back on the road and up to spec.

Good deal. Don't neglect the rear suspension while you are at it.

Suspension overhauling is a huge PITA without air tools to remove everything...

Good information though!

The rear suspension is next, Max. The purchase of 2 new ABS sensors resulted in a temporary diversion of funds earmarked for that purpose.

By the way, thanks for your advice about placing a B&M transmission fluid cooler in front of the driver's side wheel well. After 3 years of driving it really seems to be doing a great job. Last year when I did the 2 year flush, fluid and filter the fluid looked and smelled fresh and almost new. Obviously, reducing the temperature of the fluid is a transmission huge transmission saver.

Anyway, I imagine that when the suspension is done it will feel like I'd been driving a pontoon boat for the last year.

That's exactly when you want to do it, while it still appears fresh. Once it starts changing color, it goes downhill fast.
