PIcked up a bottle of Lucas PS additive at my local CarQuest. They didnt have any Lube Gard but the counter man had used the Lucas stuff in his Dakota when it had a similar problem.

Question. What connection is there between the PS pump and the breaks? When my PS pump is groaning, I can feel it thru the break pedal when I put the breaks on, almost like the pedal is jumping on my foot??

 

Quoting the '02 FSM: "The hydraulic booster uses hydraulic pressure from the power steering pump. Before diagnosing a booster problem, first verify the power steering pump is operating properly. Perform the following checks.
† Check the power steering fluid level.
† Check the brake fluid level.
† Check all power steering hoses and lines for leaks and restrictions.
† Check power steering pump pressure."

 

My PS does it too. at -10 it is loud enough for the morning walkers 3 blocks away to get off the road thinking a monster truck is loose.

I looked all over for the Lucas conditioner but only could find a Lucas PS stop leak. Is this the stuff? There weren't any other additives for groaning PS that I could find. Several other stop leaks and several PS fluid replacements.

I'm going to look again for the Lube Guard.

This is only a small town and the auto parts stores roll up the carpet at 6 PM sharp so Wally and FleetFarm are the only stores I get to locally.

 

I had that same problem the other day groaning when I turned and braked it was not that cold though about 40f

 

You can order Lubegard online here http://www.lubegard.com/order/order_form_uscan.html

You want the Power Steering Fluid Protectant

It may be cheaper to buy it locally, I usually pay about $5 for it at Napa

Make sure to suck an equal amount of fluid out first with a turkey baster or suction gun. The bottle of Lubegard may not seem like much but it's enough to overflow the system if the PS fluid is at the correct level to begin with.

 

same here.. but if i let it warm up a bit more it goes away. i'll try putting synthetic in.

 

-10F is the point for mine too. Nothing until it hits that point, then it howls until it warms.

 

I was prepared to suction out some of the fluid to put the Lucus stuff in. But when I pulled the dipstick out, I discovered that I was, in fact, low!

So I added some lucas and have not had a groan yet!

I called Napa for the Lucas conditioner but only could find a Lucas PS stop leak.
I also looked at the Lucas web page and showed only the stop leak. Is that what you used. I see "Wings" had the same question.

 

Yep it's the same stuff.

 

Yes, Jack's correct. It IS the same stuff and I'll report that it DOES infact cure the nasty groan!!

 

Ok, I finally found some LubeGuard. at the local NAPA store. It was laying down behind some other stuff on the shelf.
It was the only bottle they had. So I drag it out and start reading the label and it says.." not for systems using power steering fluid in conjunction with brake systems."

What gives??? I know everybody uses it but is it really ok???

I stuffed the bottle back down under another std PS additive so I can go back tomorrow and get it. haha It's the only bottle in town and I haven't got the only 'groaner'.

Let me know it's really ok and I'm taking off work to go and get it. LOL

They have some really nice tire valve extensions for duallies too. I'll pick up a pair of them too.

This came up over the weekend on NWBombers, too.
I picked up 2 bottles last week and neither had the new labeling.
Well, I sent off an email to Lubegard yesterday explaining I use it in my Dodge pickup with hydraulic brake boost and received this reply today:
I don't think they worded the warning note very well. Wouldn't it be easier to say "DO NOT ADD TO BRAKE FLUID!" ?

Well, I can safely flush and re-fill my system again this weekend. I think the non synthetic parts of the Valvoline PS fluid wore out this winter. Another -35° night. Getting really tired of this. I had to get the winter parka out of the closet last week.

I've got Royal Purple Max-EZ PS Fluid in mine and never heard it groan until I left work today... I think the high was 12° today...

Thanks for clarifying this. I'm headed down to NAPA and dig out my hidden treasure. haha

I think I'll just take and old sock out and soak up a bit out of the reservoir since I don't have my tools with me.
