ABS Actuator leaking on a 1993 Infiniti Q45

[elwesso]

I removed mine, and the hardest part is that the fender liner has to come out to remove the lower bolts on that bracket.. I would stay an afternoon (4-5 hours) on jack stands would be a fair estimate..

Well that time has come AGAIN!!! I need to replace yet another ABS Actuator and I barely pulled the old one apart.

What is needed to put a OEM 1994-1996 Q45 ABS Actuator in a 1990-1993 Q45?

This time I am replacing it myself!

I have a good one out of a 93 sitting around, Paul. Gimme a call or PM me an offer...

So does anyone know where I can get some tips on how to rebuild the ABS Actuator from a 1990-1993 Infiniti Q45? I will be calling A-1 Cardone to see if they will let me talk with a tech for some assistance. But I know I am waisting my time. And then if that does work comes the part where I must find replacement seals. I have already separated the actuator from the rest of the assembly and I have removed every accessible bolt, screw and valve on it.

All this after I placed my order at a discount (OEM) parts dealer.

Lokim you have (Voice) mail.

just replace with a professionally rebuilt unit, much easier and hopefully done better than diy.

I will but I was hoping to learn...

If the ABS unit you're disassembling is a spare and you're not concerned about getting it back together then start disassembling.

From my few years experience managing our valve shop at work (rebuild after every test) I think you're going to find that the ABS rehab is going to involve nothing more than complete disassembly of the unit, cleaning it up, replacing all the o-rings, and then trying to figure out how to put it all back together. Take pictures.

My suggestion would be to go online and find a listing of the Parker line of o-rings. They have every size, diameter and material of construction of any o-ring in the free world. Since all the measurements will be in whole number millimeter increments (i.e. 3mm x 22mm, not 1/8" x 29/32"), get a good set of calipers to measure the material diameters and o-ring diameters in millimeters. An o-ring sizing cone would also be helpful. Find a local shop that stocks and sells Parker o-rings (it won't be the local Ace Hardware) and start the rebuild.

Thanks Mike!

I called A1-Cardone and as I expected I got nowhere... I can't believe that with all the 1990 Q45 ABS Actuator failures no one cared enough to tear one down and rebuild it, then post helpful information. But I suppose from 1990 to say 1999 (Give or take some years, Yahoo board...) people simply paid to have it fixed and done with.

I did not take pictures as I should have but with my new spare I will remove each valve one by one and take pictures as each one is removed.

Shipped it today, Paul. Sent it Priority Mail, so I'm thinkin' you'll have it on Wed.

I used a 95- (or was it a 96) actuator on my 1990 q45. works flawlessly, and it is a better design.

Is the 1994-1996 Infiniti Q45 ABS Actuator a simple bolt on thing for a 1990-1993 Infiniti Q45?

[elwesso]

I believe the lines are in different places.. it might be bolt in other than having to move the lines around, which is easier said than done.

[Infinitiguy19]

I agree hence my apprehension to use a 1994-1996 Q45 ABS Actuator.
