Ok, here is the story
my mechanic is a nice guy but for some reason i feel like he skips certain things when he does the work but nevermind that
here is my sad story... the car has about 120K and the i felt vibrations, bla bla bla and it turns out i was right the h/b went bad
so the next morning my mechanic replaced it with a brand new stocker
this piece went bad in about 3 weeks
so i pulled an h/b off a fox motor the guy had in the shop and we put it on
seemed fine for about a week or two and today the car started jerking when i take off a light, while parking, at idle..
so i thought it cant be the h/b again but it turns out its wobbling again
WHY IS MY CAR HATING ON THESE H/B's?? do i put a new replacement piece on, go sfi, is the crank damaged, pullies ?? ideas pleaseeee

thank you guys :SNSign:
 
I went threw 3 stock (2 autozone and 1 advanced) no name HB's and all went bad within 5-6k miles. I got a pioneer non SFI unit and been good for 2-3yrs (although I dont drive it much) and have heard great things about the brand.
 
the 94-95 HB is kinda known as a failure issue. If you drove it with a bad HB for awhile you may have damaged some bearings as it can cause an un-even load on them. If your really worried about it put a oil press. guage on it and see if its got low pres.

Make sure you get a 94-95 HB the fox one is diff. IIRC...cant recall as to what the issue is but know there is somthing:rlaugh:
 
my pressure is still the same as its been since i got the car so... i think i can rule that out and replaced the front seal when i did the h/b for the very first time so no more squirting oil around the h/b
 
I could see that many going bad if they were installed improperly. If they were just tapped on vs. using the correct installer tool, it'd probably do quite a bit of damage to the elastomer. I can't say that's what was done of course, but it's a question that may be worth asking (so you know whether or not to switch mechanics).
 
I replaced my stock one with another from Advanced Auto, and it didn't even last a week. The shaft of the balancer actually cracked on the keyway. I checked the crank for too much end play, looked OK, so I threw down the money for a Romac. It has been fine for the last 2 years.
The Romac unit fit soooo much tighter on the crank.

I see by your post count you're kinda new!

Welcome to 94-95 :SNSign:

There are quite a few smart peeps here :D
and
Many peeps who've had lots of experience with Stangs :nice:

A quick search would have shown your experience with hb's to
be similar to many others ;)

Just wanted to make you aware of our large database of knowledge
that is at your disposal if you don't get the the info you seek from a
posted Question.

I can add myself to the list of peeps who had an OEM hb go bad :)
