No front wheel drive - Pirate4x4.Com : 4x4 and Off-Road Forum

ftoy507 · 07-01-2007, 06:58 AM

I have the petroworks 4.89-1 transfer case with the split H pattern. Petro did the entire build up of the case. Yesterday, in a competition my front end quit pulling.

Making it impossibnle for me to close the gap on second or first place.

When the front quits pulling
I still have rear wheel drive
I am still in low 4 with only rear wheel drive
The lever is not bumping the sheet metal
To get the front end to pull again I have to shift into 4wd then select low or hi
At first int only happened about every 20-30 ft, by the end of the day it was every 5-8 feet
Has anyone seen this problem? Is the split H any good? Or is it a weak link. My guess is it is the modification or removal of the detent ball causing this.

Has this been going on since you installed it or did it start yesterday?

You may have broke the little end on the front out put gear let it move around under load.

I'll bet you have a bent front output shaft. It can bend just a tiny bit and cause the problems you describe. It is vert difficult to see the bend, you almost have to remove the gear put it in some "V" blocks and check it for runout.

Problem started last week on a trail ride. I broke a transfer case mount and had to limp back to the trailer. I will be tearing it down this week. Any additional things to look for?

Well go get some hard facts and tear the thing apart before you post up all mad at Petroworks. Small companies like that live and breath on a good reputation.

So to answer the question is that a smaller pre 90's front output shaft you have in there? I don't see any mention of changing that out on their website. Hell it should be your responsibility anyhow to ensure that is done not them anyhow.

I am not mad at petroworks. The case has survived over two years of hardcore abuse.
I am trying to find out if anyone has ever had a problem with the split H or is it typically the detents. I never thought the shaft would cause this. Also I wanted to know more of what to look for.
So thanks for the input.

Mine started doing the exact same thing this weekend. When i pulled it apart it was full of metal.

Seems my rear output bearing grenaded, and the rest of the bearings sucked metal and now spin like shit. I would also gather to believe my front output might be bent.. mine would stay in long enough for me to go about 5 feet.. talk about pissed off.

I feel your pain man. Hope yours isnt as bad as mine was. Those front shafts are known to break and bent, and they are easy to change.

Been running the GRS II for 8 years. No problem with the "H" pattern. It can be a pain in the a$$ some times to shift. My friend was having the same issue you have. Tore down the case the nipple on the front out put shaft broken.

Thanks for all the input. The consensus seems to be the front shaft is bad. I will dig in this week and post the answer.
