The upper control arms usually are the problem. The location did not allow the use of zerk-grease fittings at the factory, so they usually are neve greased. Some people cut holes to add fittings. Spend $15-20 and get some right angle fittings from a Mustang supply house such as www.mustangsunlimited.com That may cure your problem. Don't forget to grease all the other fittings as well. NOTE: mine were so badly worn that grease would not have helped. The bolt was worn half in two by the control arm from lack of lube. Seth
Little red toy hit the nail on the head. Mine just started after 7 years since the last suspension rebuild.
I think squeaky upper control arms are a common problem among Fords. My one Mustang used to squeak so loud that someone once commented that it sounded like a bedpost in a porno flic.
don't forget the spring perches and insulators ....... did all three at the same time (zert fittings, perches and insulators) and that cured it .......... so far .........Robert
I've had to install the grease fittings in the upper control arm bushings of every Maverick I have ever owned at one time or another to solve that squeak. You can bet that will fix it.
I have owned a 70 and 76 Mav and they both squeaked like crazy in the winter especially. Thank god for the internet............found a tool that screws into the hole the plug comes out of. Comes with special round tool that scews into hole, wrench and several other grease needles for various suspension pieces and some grease zerts I had extra. Cleaning my stuff out lately and don't want to throw out. Can send pics to your email. $ 11.50 shipped.......like 30 bucks back in the day. Jetmeck@aol.com
