HOW TO DO AN ADVANCED SEARCH.
Mon Jul 08, 2013 3:56 pm by Admin
For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.
When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).
After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Power Steering Issues
Just finished an ls3 swap into my 944 na and keeping blowing power steering hoses. First time blew the pressure line from the ps pump to the hydroboost. Now i just blew the high side to the rack. I can see the hoses moving when turning the steering wheel, and feel a bit of pulsation as the wheels get to the end of their run, which is more prevalent turning left. Both hoses blew turning left, with the wheel cranked all the way.
Im using a used hb out of a 2000 mustang gt, stock ps rack, reman Cardone f-body pump, and hose kit from TPC.
Anyone else run into this or can maybe shed some light? Using the hose kit from TPC.

Re: Power Steering Issues
We just had the same issue. Going to try a different brand hose and see what happens. I'm thinking the hose we got was either old stock (possibly dry rotted) or not fluid compatible. I'll let you know if this fixes it or not.

Re: Power Steering Issues
We used a new hose made by Aeroquip, and it has had zero problems. Kent is talking to the the original hose supplier to see why theirs failed.

Re: Power Steering Issues
Thank you for the feedback. That makes sense. Something felt off when i was putting the hoses together. Explains why i oiled the street down twice, ha.

Re: Power Steering Issues
We looked at the original hose pretty close where it blew out of the fitting and the inner rubber lining was cracking. I'm thinking it may have been some very old stock that dry rotted.

Re: Power Steering Issues
Same here. Both hoses blew out of the fitting. When putting them together, the fittings seemed to go on too easily and the inner hose seemed a bit off. In any case, i cut off the damaged ends and reassembled for the time being so i can at least run the car to do some logging and work on the tune. Will definitely not be driving the car until this gets sorted, as i lost most of the brakes both incidents.

Re: Power Steering Issues
Guys you are putting 21st century power on older system you probably have over 1000 psi
We see it all the time in Corvettes that get a LS swap
You can fiddle around with restrictor pressure reducers, but I ask you why mess with the fluid at all when electric kits are available
I don’t know your specifics however I think what just did fits your system too in that it is independent Of vehicle manufacturer

Theyre talking about hydraulic fluid lines not brake fluid lines.

You got way off base no one said a thing about brakes
I was - AM talking specifically about power steering systems and I just said it correct ELECTRIC
No reason to waste time with hydraulic again

Re: Power Steering Issues
Doesn't electric power steering still require hydraulic lines.... I have no idea what you're trying to say

Re: Power Steering Issues
Nope Corvette C7 2014 Mustang 2015 and most any other car has no hydraulic pump draining energy off the front accessory drive
Tesla too
Between 2005 and 2015 most cars trucks were converted
Best read up on it

Ya, that won't work with hydroboost. Read the entire thread my friend.

Same to you, Boss...
True, these "electric" cars of which you speak don't have belt driven hydraulic pumps. What they have is electrically driven hydraulic pumps. There are still hydraulic fluid lines running from pump to brake booster and steering rack at similar pressure levels.

Power steering issues... could really use some guidance
Hey guys, I recently purchased a very nicely built 87 951 with an LS1 conversion. Something is way off with my power steering and I could sure use some insight. The problem is a surprising amount of play in the wheel at top dead center, and an odd non-linear feeling to the steering. Almost like there’s a delay and numbness in the steering. The set up uses a GM F-body pump and a Porsche OEM rack that reportedly was revalved to work properly with the GM pump.
Bottom line is I have no idea where to start. I don’t know if the problem is in the steering shaft u-joint (seems a bit sloppy), the pump, the rack, the valving? Any of you have some wisdom for me?
Thanks in advance.

You might be able to tune the feel with one of these...

Re: Power Steering Issues
I would start by checking u joints, rack, tie rods etc. Have someone turn the steering wheel and visually inspect. You should be able to pin point if you have any worn linkage items.
Personally, i had bad luck using a stock gm pump. Steering was noisy and plain garbage until i upgraded to a turn one pump.

Check the steering rack rubber mounting bushings. That sounds exactly how they feel when the drivers side bushing fails.

Thank you!
Just a quick note to thank you all for your ideas on my steering issues. I’ll start with checking the drivers side steering rack bushing. I really appreciate the help!
