So I need some advice on this one:
2 years ago a CV went on me during an autocross, drivers inside (tranny side). The bearing race cracked and well, u know what happens then, no power transmitted means flatbed tow truck home. Replaced all 4 CVs with the kit from PMB performance. All was well.... fast forward to today, the exact same joint blew. I haven't dissasembled for a post mortem but it isn't pretty. Luckily i flat tow the car to events now so getting home wasn't a problem. The car definitely took a beating today, put about 45 total runs (autox school x 2 drivers) on the car before it let go on Avon Tech RA tires, a few areas of the course induced some slip/grip stress. Motor is relatively stock, probably putting out about 100-110hp crank. AutoX definitely put exess wear and tear on the part, running semi-sticky tires. So what should I do, replace with another kit? OEM? Beef it up with 944 or heavy duty CVs? Any of you fellow autoxers have a solution that won't cost me a fortune? Thanks! |

QUOTE I don't hate Eric.... Anybody who does, is doing him wrong... Eric has stepped up to the plate and is offering us a bolt in replacement for NLA parts and I respect him for it... Personally, I like dialogue that identifies a problem, and a collective group of minds that figures out a problem and makes it go away. Thanks Ken (IMG:style_emoticons/default/wub.gif) But I think Jeff misplaced an endquote in the html, which led to the same in Eric Read's post. I fixed them. I was just taking a (IMG:style_emoticons/default/poke.gif) at Jeff cuase he's so damn smart and he welds like a Motha &^%$er. Make no mistake, he's madly in love with me (he may not know it yet but... thems is the facts). (IMG:style_emoticons/default/biggrin.gif) Thanks all. This has been some pretty good analysis for sure. Big thanks to Jeff. I don't know how you pick this stuff up. I'm still trying to figure out where the little bally looking thingy's go. (IMG:style_emoticons/default/w00t.gif) |
