3.8 cougar.just had my mot and failed on excessive play in the rack looked at rock auto but don't know which is correct . one/two piece mounting bush and with/without performance suspension what am I looking for?.
Year of car? Trim level?
What is the diameter of your steering rack mounting bolts? The larger ones (M16 - ish) are the 1-piece bush. The smaller ones (M12's, I think) are the 2-piece. They also have a longer sleeve that goes into the K-member, that the others do not. Either bushing type will fit in the rack.
Some folks retrofit the later (2-piece) bushing/sleeves for the 1-piece set-up. You can get poly bushings for either, but the 2-piece are more common.
Unless your car is a turbo or an XR-7, it probably doesn't have the Sport suspension. Read up HERE ON COOLCATS (https://www.coolcats.net/modifying/steeringrack.html) for more info.
It's an 86 just standard ,measured the mounting bolts got 12mm so 2 piece it is . going to drain and clean before refilling but can't find the amount of fluid I require to refill?.
Go with the performance rack, and just fill until shes full.
Ok got replacement rack already to fit came with new bushes and a pack of seals two same sized small rubber o-rings approx id 7.5mm 11.5mm od and two teflon seals different sized 11mm id 13.5 od & 13mm id 15mm od didn't find any seals on the pipe joins when I removed only PTFE tape on the threads also Manual doesn't mention anything about seals are these needed?.
The teflon seals should be used where the hoses mount to the steering rack.
Ok thanks also found the two small o-rings fit on the pipe under the nuts.
