my 1988 Mara has a slight leak at the top of the steering rack. I didn't think much of it until it sat for a month and when I went to drive it, it was almost out of PS fluid.

Is this a common problem? Can the rack be rebuilt?

Thanks in advance.

Fieros don't have power steering, unless someone added it or you have one of the prototype electrohydraulic power steering racks.

Where is your power steering reservoir? Is it near the driver's side headlight?
In that case you have one of a handful of 88 Fieros that got out before the car was cancelled.

To help correctly identify the Power Steering unit, I am posting photos of my unassembled EHPS components.

To me, it INDEED looks like you have a factory 88 Fiero power steering system.

To get the rack rebuilt, you'll need to find a competent rebuilder as there is no "88 rack rebuild kit".
But he should be able to source any seals needed after measuring them.

I would think the parts may be the same as a Chevette PS rack because the
Fiero steering racks were basically a wider version of those on the Chevette.

This is a Chevette PS rack in a Lambo kit.




NO 88 Fiero power steering parts are available

None of those pics are from the OP so we still have no idea what he has.

Oops.

It was a good answer, I didn't want to jump to any conclusions until we saw what he had, I've seen half a dozen different racks used over the years. Or maybe it's just a brake fluid leak.

There was a power steering unit that was put on the re-bodied Zimmer Quicksilver that had the pump located on the 2.8L engine and long lines running to the front. West Coast Fiero might have also offered an installation kit for the F Body rack.

They used a Merkur xr4ti power steering rack for those cars.

Fierosound- It's kinda embarrassing to make mistakes like that; Luckily, I have never made a mistake like that........(It's really hard looking at my laptop when my noise is 3 feet long!)

A number of after market setups have been used- The Merkur (Semi-factory), the F-body and even C4 Vette ones......I plan on doing that one in the future possibly- for faster ratio- with an electric pump up front for weight distribution....

Need to see a pic or two of your setup DrXtreme to know what you have and how to help

As far as I remember from what I have read over the years, the first 10 or so 88 Fiero GT's were sold with the optional power steering. I have also seen a video of an 88 Fiero test and it had the power steering. Then GM recalled all the cars with power steering and replaced them with manual racks. Some people refused to have the recall done and although rare as hen's teeth there have been reports of them over the years.

To me this was the ultimate bait and switch by GM. The test car they sent around to the magazines had power steering. People read about it then ordered their car and it did not have power steering when it came in. I would have refused delivery myself.

That power steering rack looks very similar to mine (haven't had a chance to crawl under the car). My Fiero is a 1988 Mera with factory (co I'm told) PS. The car has a Northstar V8 and PS pump in on the motor.

Any chance you can get a closer picture of the center part of rack at T location both sides? Mine leaks from top so I can't see where.

I will try to dig the rack out of storage and take a few photos this weekend.

The rack Nelson is showing is the proposed 88 power steering unit which was electric. It did not use a pump mounted to the engine. So, you likely have an aftermarket setup.
