I belive the original's are made by Dana Spicer and are High quality units ,
The replacements are out-sourced to the cheapest company they can find.

Why?
Get the truck thru warranty and SELL lots of cheap replacements with No warranty
Just the way it is now days

 

Gvandyke,
How are the spyntec bearing covertion holding up. I am in the market for a conversion, but not sure which brand to purchase. An update on the maintence, durability and would you recommend them would be appricated.
Thanks,

 

They were great until my accident 11/2/09. That totaled my truck. My 2003 F350. Maitanace was easy. re-greasable inner and outer bearings.

 

Sorry about the accident!
I am just doing homework trying to decide between Spyntec and Dynatrac kits - Dynatrac clearly uses tapered roller bearings, but I have a hard time figuring if the Spyntec bearings are tapered roller or ball bearings? Spyntec kit is about $500 cheaper for my truck (1999 F-350 Super Duty 4x4 DRW).

Is Spyntec kit using adjustable tapered roller bearings?

 

Thread BUMP

Any updates??

Today I talked to Spyntec directly that they do indeed have a kit for 2005 and up vehicles.

Forged hubs, nickle plated
spicer stubs
stainless Milemarker hubs
timkens and good quality seals
and the abs ring is machined into the spindle
And the abs sensor is sealed from the elements unlike the dynatrac kit. I'm a bit unsure how this works but willing to go for it.

$1550 + $50 shipping to WA.

Just wondering who's got experience with this setup? Pro-cons VS. Dynatrac.

 

I bought and installed Dynatrac kit last summer to my (early) 1999 F350 4x4 dually!

Spyntec had some minor delivery delays at the time - that and having a local Dynatrac dealer were the main reason's for me going with Dynatrac.

Dynatrac kit was around $450 more at the time, but it cost me another $350 or so, due to the fact that their hubs would not fit the original Ford dually (front) extenders.

I had to order new hub extenders from Arrowcraft.
Dynatrac instructions clearly point that out, but the local dealer I ordered the kit from (in Portland, OR), did not say anything about that until it was too late. It is my understanding that Spyntec kit would not have had this issue!

If your truck has single rear wheels, this will not be an issue at all.

The Dynatrac kit is well made and it solved the unit bearing problem 100%, but the next time I will buy directly from the manufacturer when that is an option

Spyntec and Dynatrac both will sell directly to the end user.

 

Thanks for the reply.

What I'd really like to find out is how far out the new hubs stick out compared to OEM. I've been told it's a marginal amount but there's no concrete numbers. I seen some pictures of dodges with this mod and holy hanna they stick out far. Out past the outside line of a stock rim. I just hope it's not the same for ford.
If anyone's got actual facts or pictures, either post them here or email me bigbird_7070@hotmail.com

Thanks!

doesnt dynatrac sell the low pro hubs now? Im sure i seen articles with them installed on Fords

 

Ya they do but I also read you need pliers to get them to turn they're so stiff. Surprising when they're only 1/8 turn *****. Also hard to see what position you're in and a bit spendy, so they're on the backburner for now.
I wanna see how the conversion kit looks as-is before I go out shelling my money for dynalocs.

 

this is the best Google picture i could find, its a Spyntec free spin kit but it looks like both companies stick out pretty far from what i found

 

im at 97k right now on my 2004 F350 but i grease my unit bearings once a year with high temp heavy duty wheel bearings grease so they still spin like brand new. If or when they go i would like to swap to one of these kits but since i grease them ever year and if they last 150k ill just go back to stock again. Also the only reason i see them sticking out so far is the companies are trying to get the bearings farther apart to be able to handle the weight stress these truck are under so the bearings have the best chance of lasting. But the 97 and older fords had free spin hubs and they didnt stick out that far at all?

 

i know im gonna get some stuff for my next comment but MM hubs F$CKING SUCK! I had a set on my ford and evertime i would turn them in they would clunk. Their spline was sloppy over the stub shaft and it was awful to listen too. Plus last winter i was going down this trail and went to go over a semi small hill i come over the top of it with the tires spinning and the drivers tire hit a dirt patch with no dirt or snow and POP! i blew the MM hub into pieces. The next day i went to a truck store bought Warn's and havent had one clunk, bang or broken hub since then.

 

It probably will not help you much, but in my dually truck the Warn hubs stick out only 15/16" versus the wheel studs sticking out 1 1/2", past the outside surface of the rim!

The Warn hubs turn smoothly and there is no clunking

 

IS that new hubs with a unit bearing conversion like a Dynatrac or Spyntec swapout?

Or just plain jane new hubs with OEM hub bearings?

 

It's a Dynatrac bearing conversion kit that came with Warn locking hubs.

Please read my earlier posts above on this thread, they explain it in detail
