I did this in my 94 LX with the splitport 3.8L N/A, 4R70W, and FRPP centersection.
I left a stop sign at WOT, the tires spun for a few feet then hooked, and POW! The stock front diff mounts allowed the centersection to twist too much, breaking the halfshaft and rear diff cover in the process.
I haven't had any problems since I installed poly front diff mounts and SC "fat shafts".
Yeah....I really wasn't too bummed about it when I had to call home for the truck and trailer. I was kind of waiting for that puny halfshaft to go, I just didn't expect the diff cover to break. :zdunno:
Just had my Passenger side one rebuilt on the SC. Took it in because the boot was leaking. Turns out the reason was that the carrier housings were bent! CVJ Axle here in Denver replaced both ends with new. I’m guessing the reason they got bent is due to the slop in the stock (deteriorated) rubber front diff mounts. With our TCI Street Terminator equivalent tranny, the hard shifts didn’t help it any. Poly or aluminum is the only way to go.
On a side note; 92bird has been running around with V8 shafts in his SC for the last several years. A ~350hp motor, Early M5R2 five speed, 3.27 gears, and lots of spirited driving, should have taken their toll on the shafts if there as weak as everybody thinks. But they are still tight and perfect and will keep running on them with no worries.
i have had a sc come in the shop with a leaky one and we replaced the whole shaft, was inside coming apart , now i have destroyed 2 8.8s in my f150 , never seen any through here other than noisy bearings.
Yes there are other threads on the subject, but I haven't found one that addresses both at the same time.
I have a 1996 Mark VIII.
It is tuned with Quarterhorse and has dual cat back exhaust which has made a difference up top/on the highway for sure.
Around town though, it is still...
Not sure if any of you have seen this, but this would make the rear hub swap much more affordable. I was going to re-drill my purchased hubs, but @99.95, I'd rather have new with zinc coating.
Maybe I'm just dreaming here, but that's why I'm asking. I've been driving my dad's '99 Explorer for the last few days and I really love it, specifically the tranny. The five-speed auto does a great job of keeping the SOHC 4.0L V6 in it's powerband, and it is sweet to get on it and a shift only...
I was wondering who uses overdrive (O/D) when driving around town (speeds under 55). I am always flipping the O/D button depending where I am driving. Does it cause wear to the trans. if the O/D is disabled for extended times. At constant highway speeds I always enable the O/D.
When accelerating then letting off the accelerate Im getting a slight clunking from the rear of my car, it's mostly when the car is cold, sounds like something is knocking back and forth in the trunk area, haven't got a chance to get her on a lift yet. Not sure if this is a problem people run...
