Need to replace 460'd 89 Bronco motor mounts..?

My 89 Bronco has a 96 460 with L&L motor mounts which have failed again for the 2nd time in 2 years. The rubber seperated from the metal plate and when it did, the motor jumped, took out the remote oil filter line and I lost all oil in about 20 seconds... Never again... I'm looking at Advance Adapters ( Autofab ) comp style mounts but they require removing the stock frame mounts from the frame... Anyone ever used these and how much of a PITA is it to swap to these with the engine still in ...?

Yeah, I talked to them about it. Needless to say, I'm not interested in persuing them for a fix as their product just doesn't work for long... Both of their mounts failed in the exact same way so I'm done with them... I don't have time to get into a p*ssing match with them...

If you don't mind me asking, what vehicle did you get the 96 460 from and how difficult was the swap?. I am wanting to have mine converted over after I get back from Iraq, but was trying to avoid an older motor. Thank you for any and all help.

Got mine from Leanard VahSHoltz of Pikes Peak Hillclimber fame. He's sponsored by FORD and got a bunch of motors/trannies after they were pulled off the assembly line when the truck they were intended for was pulled for quality inspection... Mine came from a 1996 F350 and had the E4OD tranny bolted to it ... Physical swap was pretty straightforward using stock BW 13-56 t-case, new radiator, L&L Motor mounts, fabbed tranny shift linkage, new driveshafts, remote oil filter... Toughest part was converting 89's firewall harness to 96 engine/tranny harness... Used HELM schematics for both years and spent alot of time splicing things together at the firewall... Also had to buy 96 460 PCM...

Why are the Motor Mounts failing? Is oil dripping onto them? I know that oil loves to eat rubber mounts over time for sure...

I use the L&L Mounts in my 460 powered Bronco and they are Great! No problems and that is even after a few dozen childish Brake stands to smoke nearly junk 32x11.50 tires.... (my buddy works at a tire shop so I often get tires to do smoke shows with.... Immature I know but its fun... even if I am 37 )

Also use F-150 extended cab heavy duty springs in your Bronco. I did that in my 84 when I put my 460 into my Bronco. Those springs have the same install height as the springs for the Bronco's but they have 400 lb more load capacity. Those HD F-150 springs may be the same as Standard F-250 springs.. Most Good parts shops have Coil Spring books with provide all the details about each coil spring listed in their catalog...

Did L&L replace the Mounts for FREE?? That is the question!

yes, they did replace the mounts for free. but the just broke on me again. right now i'm running a chain, not a very good idea but i need to drive, and i made up a set of mounts myself that i have to install. they are solid but i am squeezing 3 pieces of conveyer belt rubber between the frame and the mounts. hopefully my welding will hole of better then L&L's fabrication.

here is a link to another place that builds a direct bolt on swap motor mount for this application, there is a guy running a bronco with a 598 stroker in a drag racing that is pulling mid 10s in the quarter using these motor mounts and isn't breaking them so they must be tougher than the L&L stuff (and he said he originally had L&L, and had the same problems with failing) if that doesn't work I went to solid mounts but you probably dont' want to do that in a street driven vehicle but if you do I can probably get you a phone number of the guy that built mine just PM me (I don't want to put someone elses phone number on an open board)
anyway here is the other place.
click here

it will give you the FTE page about supporting sponser but there is a link that says to go to the site you clicked on click here, and it will take you too it.

I've used Autofab mounts in a couple trucks and have been extremely happy. They are built well with hard abuse in mind.
